Info had a cart where harried employees could put down go-backs while waiting for a free moment. This cart was almost always piled with things that needed to be put away, usually haphazardly piled unless someone straightened it out of necessity to make room. A man approached the information desk and, without even looking at the employees, dumped his armload on the cart's already sizable pile and walked away.
A few minutes passed and the Info Slaves finally get a free moment. Knowing that the Info cart is one of the closing tasks required of them, they descend upon the cart like a pack of dogs on an unguarded steak and vanish into the sections of the store with their prizes. The cart is picked clean.
Fast forward to a full hour later.
Dumbass Crusty: Where are my books?!
Info Slave: What's your name? If it's on hold we can retrieve them.
Dumbass Crusty: I didn't leave it. My pile of books was right there! *points to the empty cart*
Info Slave: *blinks* You put them on the Go-Back Cart?
Dumbass Crusty: I left them there! You should have known not to put my books away.
Info Slave: Did you tell anyone that you were still shopping?
Dumbass Crusty: No!
Info Slave: Did you put your name on them? *gestures to a pile of scratch paper and pens in plain sight*
Dumbass Crusty: NO! I put them there! You should not have touched my books! I was going to buy them.
Info Slave: So you just left a pile of books in a random location, without telling anyone that you wanted them held, AND without putting your name on them?
Manager, trying to diffuse the situation: Sir, do you know any of the titles you selected?
Dumbass Crusty: I don't remember.
Manager: Okay, do you know which subjects you got them from? *she gestures to the clearly labeled sections of the store*
Dumbass Crusty: No!
Info Slave: ...
Manager: I'm sorry sir, but unfortunately there's nothing we can do to help you.
Dumbass Crusty: Service is horrible here! I'm never shopping here again!
Manager: Thank you very much, sir. Have a wonderful rest of the day.
Thank you kindly, sir, we never missed your non-existent patronage.
May all your customers be nice.
