why would a company fire you for saying a bad word to a customer instead of just writing you up or suspending you?

@MarineBob Not only that but on average a disgruntled customer will tell 17 other people about their bad experience with a business due to being disgruntled over it…their relatives, their friends, their neighbors, their church people, their coworkers. The word can spread like wildfire and it’s even worse in smaller towns.
