I was out with some friends last weekend, and the server brought us one bill. We did our best to figure out who owed what for the meals, and then how much we should each leave for tax and tip. I hate this moment. Somebody always cheaps out on the tip! We were $5 short. So my friend whips out his cell phone and goes to the "tip calculator" function.
Where has this been all my life? He puts in the total bill amount and the number of people contributing and says "Tah-dah! Everybody owes $5.35 for the tip."
I love it.
What's your favorite method for calculating the tip, or splitting the bill? Do you have any horror stories about people who refuse to pay their fair share? How do you call someone on that kind of behavior?
