I have a story from my years at Sears outlet.
one night I'm up in the clothing department doing the usual jerkin around trying to to be bored, when a customers walks up asking if they can buy some clothes with a Sears gift card. noticing it's a Sears gift card and not a sears: Outlet I tell the lady that chances are you can't use this card for the purchase. she of course doesn't care and asks me to try and run it anyway. which I do until the last step to where the card is declined. she asks me to pull some sort of magic trick to make it work. I tell her I can't get it to work, so the best bet she has is talking to one of the managers we had on duty down stairs.
while all of this is going on we chat, tell a quick story or two, overall i thought it was a great exchange given how customers USUALLY react to something not going their way. I try a few more times, and I tell here "yeah I cant do anything with this" "it's a sears gift card and it wont work on this machine, maybe get the manager to help?" to which the lady tells me "ok", "thanks for all your help" and she goes down stairs. I'm satisfied that I did the best i could and to the best of my abilities.
next day however the manager that spoke to the woman asked me to come to the back. she then told me how irritated the customer was that I wasn't able to get them what they wanted. I explain that there was no way I could have gotten a gift card that isn't for this store to work here. but nooope! NOOOPE! the customer was upset that i wasn't helpful enough and that I didn't do anything to help her purchase a pair of fuckin bras or something. and I was getting reprimanded over a customer who was too fucking dumb to figure out her gift card didn't work. and because I COULDN'T make her satisfied. I was getting in trouble for it.
it was the most infuriating moment in my life. I'm amazed I didn't pop my lid and go off on her and just storm out of that shitty store.
