Why does Taco Bell have an app? What is its purpose?
Many of their stores don't have cashier's. You have to use a kiosk or the app.
The other day I was at McD's and an elderly lady was stressin' it because she had no idea what to do. There were two cash registers but nobody staffing them and a disorganized group of people waiting for their food and not even a clear queue for the people behind the counter to see that somebody was waiting. She asked me what to do and I told her she could order at the register but a minute later I realized I was standing in front of the register waiting for my food and that probably the workers wouldn't see her. I stepped out of the way and made sure she was highly visible at the register and when I got my food I told the worker that this woman was waiting for her food and she seemed quite annoyed but I didn't feel I could take it for granted they were paying attention.
