When it comes to tipping, most people think that the suggested numbers offered to them when they get their bill at a restaurant and correct.

But a customer at a Cheesecake Factory restaurant decided to sue the place after he discovered that the suggested tip guide was wrong.

Marcel Goldman is the man who discovered the error and he decided to sue the restaurant because the suggested tips on his $38.50 bill were between $11.50 and $16.94 for 15-20%.

Goldman noticed the numbers were off and that the restaurant had calculated the numbers based on the total bill of his table instead of just Goldman’s portion because the bill had been broken up for each person.

Goldman’s attorney Julian Hammond said, “Consumers should be aware. Why are we left to our own devices to do arithmetic acrobatics when the suggested gratuity represented is not true? The mathematic calculation is misleading. It must end; it needs to change.”

Here’s a video about a man that also made some noise when he discovered that the Cheesecake Factory locations he went to in Valencia, California did the same thing.
