I used to have an employee that the other manager wouldn't let me fire despite his absolute stupidity with customers. I managed a bike shop...a big one. 3 million a year at my location, an absolute massive amount of space and bikes. One of the things I really emphasized was the customer service, and talking with customers in the most organic way possible.
I was checking in a gals bike--I assumed she was probably a freshman at the university--and after I gave her the run down on what was going on with her bike I got ready to put her info into the computer so we can contact her when its done/track purchases. So I said, as usual, "can I get your number?"
This dude, without flinching, says, "I know she's hot, but you're married... should you be taking young girls' numbers at work?"
So not only does he make the situation awkward by creating a tension that never existed, but he ends up calling her hot, to her face, in front of a manager.
The girl went red in the face ... and her father called an hour later saying that someone made a sexually charged comment about his 16 year old daughter. Best part? The university in town was going through a massive sex scandal with the football team so folks were really sensitive about young girls being preyed on.
It was a hellish mess to clean up.
Thinking about it makes me want to kill the man.
