Hello everyone! OP here. Anyways, it was pretty funny after a while how all the guests kept trying to make small talk about the heat while I was visibly sweaty and annoyed (attractive, I know.) Luckily we have a shuttle and I periodically just went out and sat in it for a few minutes with the AC blasting in my face so it helped a little. Also, my boss called in a technician the next day who fixed it. Hopefully it doesn't happen again because it was horrible and having to wear long sleeves, a vest, and a tie as the uniform didn't help! :(
