There are plenty of FB groups and communities dedicated to wait staff and airline staff, where they can vent about customers. Most of the time, I don't quite understand what they are so on about. For example, there is a meme about an airline passenger being unable to get into the bathroom with a pic of a flight attendant laughing. Huh?
I read these things, and my first thought is, "You ARE customer service--no doubt about it--so why are you complaining??" It's not like you've just finished up a rapid response on someone, and you are getting yelled at because you didn't bring fresh water to someone fast enough.
I just don't get it. Everyone is entitled to vent about demanding people in customer service, but my compassion meter is broken when someone in customer service is having a fit over a passenger or customer asking for a glass of water.
