If we think about it in the context of a fanfiction, there could be a deeper plot. Maybe the grocery store is a place where different universes collide. Naruto and Cinder are brought there for a reason. There could be a hidden prophecy that they are the ones who can save both of their worlds from a common threat. So their meeting at the grocery store is the start of a great adventure. They might start off not trusting each other but as they face challenges together inside the store, like fighting off strange creatures that appear, they start to bond and rely on each other.
Well, Naruto might start chatting with Cinder right away. He's very friendly. He could offer to help her carry her groceries or something. Cinder, on the other hand, might be a bit standoffish at first. But Naruto's positive attitude could gradually break down her barriers.
A possible scenario is that Naruto accidentally bumps into Cinder in the grocery store. Cinder gets angry as she is not used to such clumsiness. Naruto apologizes profusely. As they start talking, they realize they both have unique skills. Naruto could show off his ninja skills like cloning himself to help Cinder find items faster. And Cinder could show some of her magic tricks which amaze Naruto.
Perhaps in a crossover fanfiction, there's a magical grocery store that exists between their two worlds. Naruto and Cinder both end up there by accident. Naruto is excited to try new things and Cinder is more cautious. They could form an unlikely alliance as they deal with the strange storekeeper who has his own motives for bringing them together.
Well, it could be that Naruto meets the Hokage in a different time - space. They might work together to change some important events in the history of the village. For example, preventing a great disaster or changing the fate of some important characters. And Naruto could learn a great deal from the Hokage's wisdom and leadership in this encounter.
Well, in such a fanfiction, Naruto might learn new jutsus from Fuu. Maybe they go on an adventure together to find a rare item or to save a village.
Well, Naruto might gain some new powers from Kami. Maybe Kami would teach him some super - secret jutsu that could help him in his battles against powerful foes.
Another aspect could be a more personal connection. Naruto, having grown up without his parents for a long time, could understand Kunou's situation in some ways. He might offer her advice on how to deal with the pressures of being a princess and a ninja - in - training. Their meeting could be a turning point in Kunou's life, inspiring her to be more confident and to strive for greater things, like Naruto has always done.
In a 'Naruto meets Rias' fanfiction, there could be an interesting exchange of powers. Naruto might show off his ninja skills like the Rasengan to Rias and her group. Rias, on the other hand, could introduce Naruto to the world of devils and their unique abilities. They might team up to face a common enemy, perhaps a powerful dark force that threatens both the ninja world and the devil's realm. Maybe Naruto would be a bit confused by the different rules in Rias's world, but his determination would help him adapt quickly.
One possibility in the 'naruto meets zelretch fanfiction' is that they team up to face a common enemy.

They might also learn from each other, with Naruto teaching Zelretch about the values of the ninja world like loyalty and perseverance, and Zelretch showing Naruto the vastness of the magical world.
Well, Naruto could teach Aang some of his ninja techniques like the Shadow Clone Jutsu. And Aang could show Naruto how to control the air currents for faster travel. They might also team up to fight a common enemy, perhaps an evil spirit that threatens both their worlds.
In this fanfiction, Naruto might be amazed by Sebastian's elegance and butler skills. Maybe Sebastian would be intrigued by Naruto's ninja abilities.
