I'm at the school cafeteria, buying some tea and a banana.
The guy in front of me in line is getting a lecture about if he just brought his own tea bag and mug he could be saving "up to $2.25!" from the cashier.
I prepare myself for a lecture on my tea as well.
Cashier: Hi...wait a minute, that's not one of our bananas.
Me: Uh, yes it is.
Cashier: No, I don't recognize it.
Me: You know what every banana looks like?
Cashier: Yes. (completely serious)
Me: Well I got it from...really?
Me: I don't know what to tell you, I got it from that bowl.
Cashier: Okay then, if you say so, that'll be $2.75.
