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.
