I HATE this other theatre company

my school has a really big theatre with an even bigger back stage. sadly for us (me) there is another company that rents out our theatre twice a year to put on a show. I hate this company because the owner/director always tries to make me do shit for his show. uhhhh no? I don't work for your company, ive NEVER worked for your company, I will NEVER work for your company, and I don't get paid by you or anyone to do this. last year I ran our social medias and the Mr.D (dickhead) kept trying to make me post on the other theatre company's account for free!!! bitch please. and then this year he tried again to make my props team and I make shit for this show. I told him no and that me nor my crew worked for him. never in my 15 years have a seen a GROWN. ASS. MAN. throw a fit over and CHILD saying no to something they aren't supposed to do..... I hope next year they get caught for their child labor, they don't play their crew or cast or even stage managers minimum wage, in fact I pretty sure it's less than 5 buck. yikes....
