What about when you pick up or take it to-go? When I sign for my CC and see the tip line I feel bad if I don't leave anything there.

Hey, Louie!

I usually pay a buck when I'm picking up. Do you think that's alright?

I think that it's alright. I have a minimum amount like that too, usually $1-$2. The same rule applies for me if I get something under $10.
