(I work at a large department store in the handbag department, we are required to check all returns to make sure they are not used and not outlet products. One brand that we carry has different linings in the bags for retail stores and outlet stores which makes checking them very easy. One day I had a customer come into return a bag from this brand.)
Customer: Hi, I have a return. My friend gave this to me as a gift but I don’t like it.
Me: (I take one look inside the bag, see the outlet lining. I mentally sigh and prepare myself for the following conversation) I’m sorry ma’am I can’t accept this bag as it is not a (department store) product.
Customer: What do you mean? You sell this brand here.
Me: We do however if you look at the lining in the bag here, this is the lining for the outlet products, ours have a different lining.
Customer: Can’t I get something for it.
Me: I’m sorry ma’am but as it is not one of our products I can’t take it, even if I wanted to my system won’t allow it.
Customer: Can I at least get store credit.
Me: No, as I said, it isn’t our product and my system will not let me process it as a return. I would suggest taking it to the outlet and see if they can help you. If not, it is a nice bag you can always re-gift it.
Customer: (angrily grabs bag and walks away mumbling about terrible customer service)
Me: (turns to coworker) why does anyone think they can return a bag somewhere it wasn’t purchased at just because they carry that brand?
Coworker: People are idiots

At our drive-thru convenience store that doubles as a gas station, I was waiting on a customer in the drive-thru when this exchange took place.

Customer: “I just want [a couple of small things].” *Hands me two dollars*

I step inside, ring her up, then return to her vehicle.

Customer: “Oh, I need a few more things. Just let me know how much more you need.”

I ring up the additional items and again return to her.

Me: “I need $3.28 more.”

Customer: *Hands me 3 dollars and a quarter* “Keep it, I’m not worried about the nickel.”

Me: *Blinks at her* “Okay, thanks.”

I figure, we have penny dishes – I’ll just toss in the three cents and not say anything this time. But I still can’t figure out how she thought she was giving me 5 cents over what I needed….

(A nicely dressed family comes into our store on a Wednesday evening. Our store is just outside of Chicago, IL. This is relevant.)

Mother: I’m looking for (item)?

Me: Of course, they’re right over here.

Mother: Okay, great! And do you accept chaaaaage caaaaahds?

Me: (taken aback) I…I’m sorry? (luckily it was loud in the store so this didn’t seem odd.)

Mother: (louder) Do you accept chaaaaage caaaahds?

Me: …Oh! Yes! Yes we do!

(The family was from New Hampshire, and they were a little miffed they had to pay tax!)

I work at a store that offers shredding services typically we weigh whatever someone brings in and charge them by the pound. One day someone came in with a bag of junk and the following exchange happened.

Customer: Hi can I put this stuff in the bin to be shredded?
Me: Sure, let me just weigh it first.
(He brings it over to the scale and I start to weigh it.)
Me: Ok, looks like that’s about 5 pounds so…
Customer: Wait do I have to pay for this?
Me: Well yeah.
Customer: Yeah ok, I’m just looking to get rid of this stuff. Is there a trash can anywhere around here.?
(I don’t offer him our trash can because I don’t like the idea of someone coming in just to give us trash. I offer him a the dumpster outback that we share with some other businesses and I don’t care if he uses it.)
Me: Well there’s a dumpster outback you can use.
Customer: Ok great. Is it ok if I go out this way?
(He starts heading to the back towards the direction of the dumpster, only problem is there’s no door back there just two in the front.)
Me: Well no, there’s no door there, you’ll have to go out front and go around.
Customer: Ok never mind then.
(He then leaves, gets back in his car, and drives away. I still don’t understand why he couldn’t be bothered to walk around from the front, but would have had no problem walking out if there was a backdoor.)

I work in a restaurant that at the time served only barbeque. So, this nice elderly couple comes in and approach the counter to place their order.
Cashier: Hi, welcome to (restaurant) do you know what you want to order?
Lady: do you serve anything other than barbeque?
The cashier tells them no and the customers say ok and wander off
