It’s very convenient when a restaurant calculates and prints out the suggested tip percentages and amounts. It would also be helpful if those percentages were calculated correctly. 20% of $19.97 isn’t $10.25. That’s actually more than 50%.
Anyone who knows anything about math will find this calculation of theirs quite odd and wrong. Is this business relying on drunk customers who don’t pay much attention to what and how much they are paying or people who flunked math?
