From RHUer, February, 2010:
Hey, so I work at a really well known craft store as a supervisor, and I've honestly never had a terrible customer until today.
So, I was ringing people up on the only open register, and I'm trying to go as fast as I can so no one gets upset.
A woman (who, by the way, already seems disgruntled) comes up with fake flowers as well as one glass vase and one metal vase.
Now, our scanners can be super-sensitive and scan things twice sometimes without even realizing it. This happened to this woman's large metal vase, but wasn't noticed until after she already paid.
So, I apologized and said I'd take the extra charge off and it would go back onto her credit card. Most people have no problem with this.
But no, this woman was obviously upset, but let me do the transaction anyway. About half way through the transaction, she moves her arm, and the METAL vase falls to the floor.
It makes a lot of noise, but other than that is fine, and I even offer to go get a new one in case there is any damage done.
This makes the woman incredibly angry (but still calm). She then turns to her husband and says, "First you charge me twice and then you drop it on the ground. Is she stupid?"
AM I STUPID????
The scanner is overly sensitive and you can't move your stuff so I can put the vase somewhere AWAY from the scanner, knock your OWN vase over, and then ask if I'M the stupid one???
After I, along with the other 4 customers in line, hear this, and I immediately stop my bullshit sunshine-happy attitude, and finish the transaction as emotionless as possible.
After I fix the problem, I again apologize for dropping the vase and it scanning twice on accident, and she asks for my name so she can go complain about me.
The next customers were incredibly nice about it and even told me that the woman must have been stupid because I was doing such a great job, and even told one of my managers so when I explained what had happened.
