Retail horror stories

[buckshot]

i know there are a good number of retail workers on here. we hear a lot about the horrible experiences customers have a walmart, best buy, etc etc. having worked in retail for a few years i've accumulate more than my fair share of horrible customer interactions. my favorite is:

While i was working at home depot working the self checkout. a customer came through and with a long piece of crown molding. he scanned the barcode and since its sold by the foot my computer prompted me to measure the length. "sir, i just need to measure that so i can ring you up."

"its 8 feet" he says.
"still, i have to measure it." i reply
"why, its eight #%*@% feet"
"well normally i wouldn't care, but my boss to my left (pointing to boss) appreciates it when i do"
"i don't care, its 8 god $#!^ feet."
this back and forth continues for a few minutes.
"listen man, you could have been done by now, just let me measure it and we can move on."
"FINE $@#$%#@$ YOU!"
at this point the customer throws the molding at me like he's leonidus or something. i move so it doesn't hit me, which it would have had i not. the customer then smashes a tile he was buying and stomp out shouting "F#@# home depot. Bunch of #@#$))*$P:">. AND }"?">$_$>@}!&)&^( YOU TOO!"

As he walks by i smile and say "have a great day sir, thank you for shopping at the home depot "

"**** YOU!!!!!" he replies as he walks out.

i measured the board. it was 10 feet.

anyone else had bad experiences from the other side of retail?
