Who’s counting

A conversation overheard in a bar;

Gentleman 1: “I believe in what you are saying 110%. Howard.”
Gentleman 2: “Ugh.”
Gentleman 1: “What?”
Gentleman 2: “Why not 120%, or 130%, or more?”
Gentleman 1: “Okay, I believe in you 140%.”
Gentleman 2: “Anything beyond 100% is meaningless.”
Gentleman 1: “Okay, now I’m down to 90%.”
Gentleman 2:”That’s better.”

You can’t give more than 100% in anything!
