I've got many stories to tell from my days working in the computer/electronics section of a retail chain back in the late 90's and early 2k's. Here's the first one:
So it's close to X-mas time and this older lady comes in asking me if we sell "Drive Hard's." I'm trying my best not to laugh, and I politely ask her if she means hard drive. This sends her into a rage, saying, no, her kid told her he wanted a new DRIVE HARD for Christmas. So, I show her a box of a Maxtor hard drive, point to where it says hard drive, and say I think she just got things mixed up. This makes her even more mad and she says her son knows more about computers than I do and asks for my manager. I was the lead of the department and handled all computer related stuff, so I just told her she was dealing with the right person.
So, she takes the box, looks at it for a bit, and then throws it on down on the counter and storms off. I muttered something like "crazy old bat" and went back to work. About 30 minutes later she's back with our Operations Manager in tow. She says I refused to sell her a hard drive. He asked if that was true, I said it wasn't and she became irate when I tried to sell it to her. She denies all this, and he just tells me to sell her a hard drive and walks off.
So she's glaring at me as I hand her the hard drive from earlier. When I did I said "went home and asked your son eh?" and she says fuck you, snorts at me, and walks off. But we're not done. About 2 months later she brings in a computer she says no longer boots. We did repairs (one of the few places in this relatively small town that did), so I said I'd look at it. She was relatively nice this time. So she leaves and I take it to my work area and it's just a loose cable. But I'm don't forgive and I don't forget. So I wiped her "drive hard." She cried a bit about losing everything when I told her. In the end her "repair" cost about 400 dollars. Payback, sweet, sweet, payback.
