Your tip is good but...

A very rich patient gave me $80 dollars. I accepted so she won't feel bad but later on, I turned it in to my supervisor. It's not that it's against our policy nor it's my call of duty, but I just don't want to feel indebted to anybody. I hate the feeling of paying them back in return through your good deeds. And when you fail, they'll take it against you. To be safe, I don't accept in gratis, unless we're really close.
