However, they also have, say 4 windows open, but only 1 person servicing
two of the windows. They take someone's order and then someone else gets
the food, while they go to the 2nd window and deal with the customer

people and taking payment.

They usually do not want the same person handling the money who
handles the food. That person would need to wash their hands or put on
a new pair of gloves on every order. That is just the health
department.
