How do you treat people who you think are stupid?

You're right about the service industry. When I was doing lawn maintenance, and I was very great at it too, there were still people that felt entitled and were very condescending. And then when I worked in a private automotive garage, there was this one guy I'll never forget that had beef with me. He's tried to get me fired several times. My bosses knew about him because he's always had a target but they still couldn't do anything about it. Anyways, I think that dude bullied me because of insecurities with his long criminal record and trying to climb the ladder So it's the typical prison attitude, "my $hit doesn't smell nearly as bad as so and so." Ironically, I'd have the same cold attitude when I worked as a CO. That guy didn't like that. It was just an annoying game of dominance. The more he tried, the angrier he got. Lol

Anyways, people need to treat others with basic decency. It's not hard. But if they can't, I hope they have to learn how to do service jobs or someone they respect does a service job so that they may learn.... because otherwise, if they aren't humbled, this attitude continues until they're completely alone.

I prefer the word slow. And people can be slow in various aspects of understanding.

@Colonelmustardseed if you are in retail no matter how stressed you may feel if customers ask silly questions they should be treat with courtesy . given the help they need that goes for any profession really who deal with the general public

I don't think i'm mean to them, but i might have to speak a little differently, like over explaining things, which if my assessment is wrong, then i could see how it would come off as rude, for which i would want to be notified asap so i can get my act together asap.

I don't. There is no cure for that.

I treat them with the same kindness they treat me with
