Working in customer service be like

There's this guy who works at the Walmart by my house. He's super awkward and shy, my husband and I always felt kind of bad for him because he's a nice guy but you can tell he's gotten a lot of shit from people. One day I was in line at Customer Service and shy guy is at the counter. He seems like he's putting more effort into not being so awkward. There was a guy, his wife, and their new baby in front of me. Both parents are stressed out, the wife is practically yelling at the husband and just being plain rude to everyone. Shy guy enthusiastically waves them over with a big smile and says "You're next!" The husband goes "Oh! Hur hur, I'm next? Of course I'm next, there's nobody in front of me!" He went on insulting shy guys intelligence then started complaining about not being able to return something without a tag or reciept.Shy guys eyes went dead and all I could think is "this guy is going to f*ing torch this place someday, or shoot it up..either way this place is going down"

This is how I felt everytime I got shit from someone at the register or on the sales floor. Inside I wanted to slit their throats or beat them to death.... but I can only fantasize and let the moment pass.
