Nurses and other people who work in positions where there are night hours are called to do this all the time...many’s the time I was semicomatose on Christmas morning because I had to work hours like this. It’s the cost of being employed . Does that mean we have to like it?? Of course not, but it is a job and in this day and age, we need to keep that in mind.
It’s possible there is a big difference between tending to ill people and selling merchandise. One is necessary, the other is not.
