If they can deal with me and my friends (mainly me) and the food is relatively cheap I've been known to give 100% tip.
I always do, no matter where I am.
It's a pain in my ass convincing my parents to do the same, but I guilt them into doing it.
Unless my ISFJ sister is there, then don't even think about trying to convince her to give out a tip.
Why does she not want to tip?
Your kisses, sweeter than honey. But guess what, so is my money.
she thinks its unnecessary, they get paid to do their job. thats her answer when I ask. " THEY ALREADY GET PAID FOR DOING THIS!! ITS THEIR JOB"
Then again, my lovely sister is quite cheap. lol
