So would you go to any of these people for advice? If not simply disregard what they have to say. If you don’t value them in any way then their opinion is not worth absorbing.
Cbt has helped me with this sort of logic. I’m not saying that I don’t occasionally get someone rude and think About it all night but it’s far less frequent.
If your manager has your back you don’t need to worry about job security but don’t fire back at the customers or you could risk that. I tend to just not say anything if people go off the rails.
A lot of people diffuse the situation by discussing customers behind their backs when no one is around. Like you know how there’s the one guy who comes in five minutes to close every time…what a jerk. To your coworkers only, not in front of customers.
Another approach is venting to a friend or even here after the fact as that will clear your mind a bit.
