One character could be a young female bartender who is new to the city and the bar. She doesn't understand the local bar culture of leaving customers alone. The customers could include a couple on a date who are trying to have a private conversation. There's also an old - timer who has been a regular at the bar since it opened and is very protective of the bar's atmosphere. He takes it upon himself to teach the new bartender the ropes when he sees her bothering the customers.
Well, the main character would obviously be the bartender. He could be a young and inexperienced guy, fresh out of bartending school, full of enthusiasm but lacking in the social skills needed for the job. There could also be an older, regular customer who has been coming to the bar for years and is very set in his ways. He would be the one most annoyed by the bartender's behavior. And then there might be a female customer who is more patient with the bartender at first, but eventually gets fed up too.
The bartender could be a middle - aged man who has recently changed careers and is a bit too eager to please. The customers could include a group of businessmen who come to the bar after work to unwind and don't want any distractions. There could also be a solitary artist type who comes to the bar to find inspiration in the quiet atmosphere. When the bartender starts bothering them, it disrupts their routine and causes tension. Then there might be a bouncer at the bar who has to step in when things get too heated between the bartender and the customers.
It could also be that there's a particular customer who is really bothered by the bartender's attempts at friendliness. This customer might be at the bar for some private reasons, like to think over a difficult decision. The bartender's constant chatter makes it hard for the customer, and it leads to a series of events where the other customers get involved, some siding with the bartender and some with the bothered customer.
Fellow wizards or magic - users could be regulars. They might come to the bar to unwind after a long day of using magic. Some might be there to exchange stories about their magical adventures or to seek advice from Harry, who has his own share of extraordinary experiences. They could include a young wizard just starting out, looking for guidance from Harry, who is seen as a bit of a local legend in the bar.
Hermione would definitely be a regular. She might come to the bar to relax after a long day of studying ancient spells at the library. Ron would also be there often, enjoying Harry's special butterbeer with extra foam. Hagrid could be another regular, coming in for a large tankard of a strong, warming drink.
Imagine Harry Potter as a bartender. He could be using his skills not just in mixing drinks but also in reading people. Since he has faced so many challenges in his life, he can easily spot if a customer is hiding something or if they are in trouble. His bar could become a place where secrets are shared, and he has to use his wits and magic to keep things in order. He might also have to deal with rival bartenders from other wizarding establishments who are jealous of his popularity and unique drinks.
Maybe Harry is a bartender in a magical bar. He uses his knowledge of potions (from his wizarding past if it's in a Harry Potter - inspired setting) to make drinks with special effects. He could get involved in solving mysteries related to the bar, like why some customers are having strange reactions to certain drinks that seem normal at first glance.
Maybe Harry works in a wizarding bar. He could be using his skills and knowledge to create unique magical drinks for the customers. And perhaps he gets involved in some sort of mystery or adventure related to the bar or its patrons.
One character could be a fearless knight. He is used to fighting all kinds of foes, and when he meets the ghost, he doesn't flinch. He uses his sword and shield, believing that his strength and honor will help him defeat the ghost.
He could be hiding from a group of angry gangsters. They might have come to the bar looking for someone or to cause trouble, and the bartender, not wanting to get involved, ducks behind the counter.
Another possibility is that there could be a sidekick or a friend of the 'little one' who plays an important role. They might be the only one who believes in the 'little one' when they start to have feelings for Slenderman. This character could help the 'little one' navigate through the difficult situation of being in love with a feared entity like Slenderman. So, it's not just Slenderman and the 'little one', but also those around them that can be important main characters.
There could be students from a nearby school or college. They might come in for a quick snack or to study while having a coffee.
