I like to give a big shoutout to the subhuman mouthbreathers at my local Stop & Shop deli department, whose IQs only rival their shoe sizes.
Since I usually buy my deli stuff when I'm shopping for the week, meaning I'll be there for a while, I use the automated kiosk to place my order, and pick it up when its done, rather than what at the counter for a while to place my order.
Every week, they screw something up. So I have to check my order when I pick it up. My complaints inevitably fall into one of these categories:
1. Me: Hi, I'm order #4. The PA said it was ready, but I don't see it.
Them: Oh, it's not ready yet.
Me: Then why did you play the announcement that it was?
Them: That's the computer, we have no control over it.
2. Me: I see you gave me peppercorn chicken instead of the orange glazed chicken.
Them: We don't carry that item so we substituted this instead.
Me: The computer listed it, even said it was on sale. If you don't carry it, shouldn't you delete it from the computer?
Them: You know, you're the third person today to have this problem. I really don't know what we should do about it.
3. Me: Hi, this I ordered the store brand American cheese that's on sale. This is something different.
Them: Oh, we're out of it so we gave you this instead.
Me: It's the wrong kind of cheese and costs $4 more per lb. Can you at least give it to me at the sale price, since you ran out.
Them: But it's a different chese that costs more than the one you ordered.
Me: Can I see your manager...
Them: But he doesn't have the cheese you want either. I told you we're out. :true: (This actually happened on Saturday)
