I'm glad I don't see any of the techie guys I knew from college because they all behave this way, and also have the very obnoxious belief that anyone less successful than them has earned their lot in life. I have one friend who still sees them and I laugh whenever I hear about them racking up insane bills at a restaurant, completely oblivious to how it feels for the normal people they then demand to bill split with. They even charged my friend his share of a hotel stay for a trip he had to back out of, just insane shit

I used to wait tables and we had a regular who was a prominent local retail estate agent (like, multiple billboards with her face on them prominent). Everyone hated getting sat with her because she would insist on being sat in the party room by herself or with one person she was with (I guess she was too good for a table next to another customer's table) and you'd basically have to split your attention between two sections, neglecting your actual section that your other tables were in, inevitably leading to reduced tips from that section.

Then after like an hour and a half when she finally left she'd consistently tip one dollar. On top of being a ton of extra work, you'd generally net lose income for waiting on her.
