We're supposed to tip people at coffee shops?
Actually, thinking about it, I have seen the "tip" part on the Card receipts, always leave it 0.00. Same thing applies with burger joints/pizza places where I don't get waited on.
I honestly believe the only people who should get tips are actual waiters in actual restaurants(as they do get paid a lower Minimum wage). And delivery drivers.
Although the article does seem to be nitpicking about the gratuity added to large parties. Usually, at the restaurants I go to, the added gratuity is 10% or less. That's 11% less than what I was taught was "right" to give.
Offtopic, but I once did see a "Tip" part on a receipt for a gas station. I ignored it.
