so I was training the other day at my gym and we have a mat and it's usually pretty cool the way we share the area and let each other work in. But today there was a dick who didn't let me work in and said he had two more sets. He had it all, a belt, strap, chalk (which isn’t allowed in the gym), and wraps to hold the weight. he kept slamming the way down with awful form and then he get up and walk around the gym for about 10 minutes like he was so cool. Then he came back and did another set and then told me I have one more set after. Without letting me work in. What should I do in a situation like this would you go and complain to a manager or just let it go?
