At comics stores, you can have subscription box, where the new comics that you collect are placed inside on a weekly basis. As soon as a known customer enters the shop, one of the employees says hello and goes to the back of the store to get the customer's comics out of their subscription box.
Last week, a young bearded employee named Jake saw me come in and said really loudly "Hi Rob, I'll grab your box!"
I looked over at Torma, one of the other employees, and said, "Well, Jake can grab my box any time!" - as raised my eyebrows. I'm out to everyone in the shop and of course, no one cares. Torma got the message and laughed out loud. It's always fun to go to a store where you know the employees and can joke around.
