I used to work at a theatre. Me, and the rest of the staff, had no say whatsoever on who was going to appear, which meant I worked shifts for shows that I would never in a month of Sundays have paid to go and watch.
But when you are selling programmes, taking tickets and showing people to their seats what the show is about is irrelevant. Even when I was scheduled as one of the staff who would at times be inside the auditorium for bits of the show I still had too do my job whether I agreed with the entertainment on over that day or not.
A lot of shows I actually bought tickets for. Some of those shows as an audience member I got up and walked out. Those same shows despite me being so against what was on stage that as a loathing audience member I had walked out of I still had to stand inside the auditorium when it was my shift to work.
That's life. You go to work you do your job you go home.
