Customer: Can I get about $7 worth of shrimp.
(I grab a handful and throw it on the scale)
Me: That’s $7.57. Is that good? Or do you want me to take a few out?
Customer: Add four more. (As I add four more) I want it to be under $8.
Me: Um....well that’s $9.12.
Customer: Take out four.
Me: Okay. Here you go!
Customer: WAIT! How much is that?!
Me: It’s back to $7.57
Customer: Add three more.
