The actor said on a radio show that his father “instilled” the tradition in him.
“I grew up with having that instilled in me from my father so I’ve always been generous. For a 120 pounds meal… I’d tip probably 30 pounds, or 35 pounds… Yeah that’s about right,” Cooper said, reports femalefirst.co.uk.
The star added that once upon a time he was on the receiving end of customers’ appreciation.
“I waited tables. I was in the kitchen up until college, and then I was the worst waiter in the world for a very short time,” he added.
