An elderly mobility-aided person is ahead of you, first in a queue for the supermarket's one public washroom with one public toilet. The washroom is in the employees only area so customers awaiting comfort and relief wait 50ft or16m from the washroom.
The elderly mobility-aided person moves toward the washroom, locks the door after entering.
How many minutes elapse before you wonder if the person in washroom needs assistance or is having a medical emergency?

My personal answer is 12 minutes.
