[Cicero]

We have a phrase:

Oh you have a good one. (as in, terrible customer that you will have to deal with on your own because no one else here will handle that shit)

Or so and so has a good one!!

It is said right in front of customers, or after they have left. If it is a completely insane moron someone will stand there, or swing by, and mention it, to make you laugh so you can continue to plow through the ridiculous argument. lol

Sometimes it's yelled across the building from another work station when people can't hear it, but they sure as hell can see it from there ( the irritating customer ). Or the unfortunate moments they can hear it from there. No one has ever called anyone on it so far, so I suppose it works.
