Hi there, what can I get for you?

Do you still have the Quarter Pounder deal going on?

We don't, so that button is deactivated. But maybe if I push it anyway...

AAAAAAGH, MOTHER OF MERCY!

Next time, tell me if a button on the register will set the customer on fire.

It's a lesson we all have to learn on our own at one point or another.
