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.
Amy enjoyed a fish taco and Nora had a burrito.. 
The food items are reversed, so neither had the food item described. The system probably saw all the key words it wanted to see and passed it off as correct.
