That worker doesn’t want to be there, that’s likely one of 3 jobs they need to barely scrape by.
You holding them up from doing other tasks they need to do to keep a job that barely feeds them is doing nothing but making their day a little harder. It affects the company 0%. The company is faceless and doesn’t care how much you abuse the worker bees as long as they get your money.
I don’t know what the answer is aside from not patronizing the company at all, but I know that’s not it.
I highly doubt it, if the store is too busy they’ll likely either do nothing because why would they or if it’s really bad add some robots who can handle the workload so they can get rid of those pesky employees.
In the past few years almost all of the fast food places in the closest plaza to me have been working on a skeleton crew. Lines wrapped around the building, 2 miserable employees, upset customers, but the money is still coming in.
Most people can’t just leave their job, even a days wage can crush a lot of people.
