Mervyn's is a department store out here in CA. Not sure if they're anywhere else. My auntie got me a job there during my Christmas' break when I was in HS, or maybe it was Summer, I can't remember. Had to have been Summer since getting a job for just 2 weeks seems strange.
Anyways, this lady comes in and tries to return some stuff without a receipt. No biggie, but she can't get cash without a receipt only store credit. I explain this to her many times while remaining calm, but she's becoming more and more agitated. So finally I tell her, "Look, you can't get cash without a reciept, only store credit, would you like to speak to a manager?" (Or something to that effect, this was like 15 years ago so I'm kinda foggy on the details)
She gets all pissed, snatches the item from me and goes over to the Customer Service desk to try to get the money from them. I guess she was complaining about me to the person at the CS desk who just happened to be.... wait for it.... my auntie lol. So basically she told her the same thing and she gave her store credit, but apparently she started crying on the way to the CS desk so my auntie always gives me a hard time about "making the girl cry and Mervyn's"
So yeah, not as exciting as you think, I made someone cry because I was doing my job and following the store guidelines.
