The man can't help but want to see you again. He knows it's against the rules to get involved with customers, it's dangerous and he could be fired for it. But he can't help it, really.

"That's my number, call me if you want to play again." Or if you just want to talk, he wanted to say that but... he won't, for obvious reasons. Secretly, he feels like a teenager again, waiting for his first love's message.
