I took the tips on the bar from the bartender who served me a drink
Why did you take the tips?
I believe in taking what you can get, when you can get it
Taking another person's tips is wrong, it is stealing. You could get kicked out of the bar.
It's my right to take tips if I want to. They would still be making money even if I take the tips.
It doesn't matter if they would still make money. They earned that through working and you didn't so it's stealing. How would you feel if someone stole from you?
