Oh absolutely.

Had a friend that was absolutely minted.

Went out for dinner with him once.

He used coupons (groupon?). He complained about the food and made them bring out another plate. Twice.

He didn’t want to tip.

It was embarrassing. The food was good. He made a complete arse of himself and saved a few £/$ and was clearly pleased with himself.

Clearly these people are rich for a reason but FFS. I apologised to the staff for his behaviour.
