If they laugh at someone else’s pain. I can’t respect a person who finds joy in hurting others.

When the dinner Bill arrives and they tell me they don't have any money.
Especially if they're the one who asked me out (it actually happened).

I had to circle back to this one. I can't stand when people call me whining about something. I just got a phone call from someone whining about the service of a fast food place that they are at.

When they try to tell me how to do my job

Conspiracy theories. As soon as I hear one I disengage. That's not to say that you can trust everything that you read, or that we've never been deceived, but conspiracy theories tend to verge on the ridiculous.

Honestly, if they still support Donald Trump. I can’t understand that at all.

Rudeness

Rudeness to servers or cashiers...usually a good indicator.

When someone tells me I should discipline my son because they have a sick fetish and have no clue what it's like to raise a child with special needs

Poor work ethic

Lil dic

Constantly talking about sex

Spewing out incel BS.
Bragging about how much money they have or earn..
Excessive bragging, comparing themselves to others and acting superior in general.

Constant swearing, being workshy, smoking or vaping in my face, boasting.

Seeing a trump sign in their yard.... Or a red hat on them.

*Where did I put that damn list*

Anyone saying something bigoted/racist.

Being a deadbeat parent.
