CS is CS, whether it's on a phone, over a counter or bringing food to a table.

Well there was my friend who worked a country club, every shift since they had opened the doors. They had what he called the "fish matrix" where you could choose any of four different kinds of fish, cooked any of four different ways with any of four different sauces and sides. None of the cooking methods was poaching.

One day a waiter came back and put a hand-written ticket on the line for poached salmon. Dan asked him what was up and the waiter told him that the guest had said, "your guy in the kitchen will do it for me. He has before."

So the chef walks out to the table and says, "Sir. Had you politely requested poached salmon I would have been happy to prepare it for you. Since you lied, you'll need to choose something off the menu."

BWAH!!

And have you heard of a PEBCAK error? I don't recall where this one started but it's the IT professional's last resort after they've tried everything. "I'm sorry but I just don't think I can help you- it looks like this is a PEBCAK error." It stands for Problem Exists Between Chair And Keyboard.

I've heard of that, yes. From ND, I think.

Also "you've got an ID10T error, there."

Are you having a PHB section? I once worked for a lady who (when we were hurting for staff) called the "Bereaved Parents Association" to ask if any of their kids needed jobs. She thought Bereaved was a place.

PHB?

Pointy Haired Boss (Dilbert reference.)

Ah ... food service revenge.

A friend of mine once worked at a restaurant where the wait staff was treated like crap. The boss/manager was playing games with their pay and tips so they always ended up getting shorted a little - not enough that they could take legal action, but enough to sting. And he treated them badly in general. So ... one night, in the middle of the dinner rush, one of the wait staff rang a bell/tapped on a glass/whatever and announced that the entire wait staff was quitting. En masse. At once. And they all walked out.

Customer services hell:

Customers who think the phrase "That is not acceptable" is the key to getting what they want. "I'm sorry, sir, we don't support you trying to remotely program the computers on the space station from your Commodore 64. You need to have at least Windows XP." "That is not acceptable."

One wants to yell "I canna change the laws of physics!" but I'm sure they'd say "That is not acceptable."

(Actually, it's more often, "Hi, we cobbled together a system that goes against your stated recommendations, and our entire corporate structure is based on that system, and now we need to upgrade to your newest program but we want to keep our cobbled-together configuration." "I'm sorry, we don't support that configuration, and if you try to upgrade to the new program, it will crash your entire computer system." "But we want it this way. Make it work. Oh, and you're right, it did crash our system when we tried to do the standard upgrade, help us fix that, OK? We need our non-supported configuration back. Oh, and the person who actually did the configuration left the company two years ago."
