With many theaters having near 24-hour screenings for Endgame this weekend (one of my local theaters are starting showings at 8:30am on Friday, with a final screening at 2:50am that night and then starting all over again a few hours later), it's going to be tough for those working at movie theaters. As an ex-employee for the largest theater in my state (24 screens), I can say that this weekend is going to be madness for theaters and employees.
So, be sure to remember the ushers and concessionists that are (more than likely) going to be working mandatory OT this weekend.
They have a long and hard week ahead of them.
