OH YES THERE IS!

Customer came up to my till earlier. He puts his basket in place and starts taking his shopping out and loading it straight into his bags.

Me (jokingly): "This works a lot better if I scan your shopping first."
Customer (PO'd) : "Well there's no need for sarcasm"

All together now...

well, sir, i could have went for option two:

calling my manager AND the police to let them sort it out, rather than sarcasm, but it's your choice.

wow...

I would have said the same thing. That situation totally calls for sarcasm!

And Sheldon, I love the quote!
