In my first two weeks at a new job I’ve been asked to stay late five times

I’m a sales veteran.(8 years in the industry) Been here two weeks and I’ve had the most sales in September out of anyone else in the office. I’ve declined every single request to stay late. Of course they ask me when they make a piece of every sale I make. I see what they’re doing. If they keep asking when I say no, imagine how often they’d ask if I said yes. I work nine hour shifts five days a week. They’re getting pissed now when they ask because I have yet to agree to stay late. This job blows I’m already looking for a new one.
