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 band split the tips among themselves
