Lunch with friends<br>Amy and Nora went to the new Mexican place for lunch. They both ordered giant Margaritas and chips and salsa. Amy enjoyed a burrito and Nora had delicious fish tacos. While they were eating, a mariachi band came to their table. Before they left, they tipped the band because they were so good.
The restaurant doesn't pay the band, they depend on customers tips to earn income
