When clients remember you and wave at you outside of the restaurant

This is so funny

I see around 200 different people per day, I don't remember them at all, I only remember some who come every day or every week.

But the clients remember me. And it's so funny. They are so happy to see me outside with my friends and they wave. One woman also waved many times so that I see her - I had not noticed she was waving at me before.

Does this happen to you? Any funny stories? Like, imagine being seen doing stupid things with your friends or something
