Kill Two Birds With One Stone

Samantha trailed behind the waiter at a safe distance, and she even made sure she walked lightly. Hence, the server did not notice him, and Samantha managed to follow him until the end of the corridor.

When the server stopped, he looked around. After making sure that there was no one, he took out the phone.

Samantha did not know how he knew the password to her phone, but she saw him quickly typing something.

Samantha was hiding behind a pillar, and even though she could not tell what the server typed, she guessed that he sent out a message using her phone. 

Next, the server waited until the message was sent, deleted it, and turned off the phone. After that, he threw the phone into a dustbin nearby.

As soon as he was done, he quickly left.

Samantha appeared from behind the pillar and swiftly walked toward the dustbin. Then, she took her phone out and turned it back on.

She recovered the deleted message and read through the content.
