compassionless

A word to describe a person or people that greedy and selfish. They lack empathy for people in need or for people that have gone out of their way to provide the best care for these snobs.

Guy 1: See that guy over there in the restaurant. He is such a compassionless dick to the waitress. She went out of her way to make sure his order was right, refilled his drinks promptly, made sure the table was clean for him, double checked the order making sure all the specific requests for the food was done right, she was genuinely nice person, and he didn't even leave her a penny for a tip.
Guy 2: Yeah that guy is a fucking compassionless dick.
