Students get to take turns being the waiter/waitress and customer at a restaurant. The customers will order from the menu but must not go over a budget of $25.00. When they receive their check, the customers must figure out what %15 of their subtotal is in order to tip their server. The waiter/waitress' job is to take the customers order and add up the prices to provide them with their subtotal. They could also add the tax, but I did not include that in my activity.
