Agreed, if you can't stand a certain wrestler's match, use that time as another intermission so that you can go get a drink, food, merch, use the restroom without a line.
We aren't familiar with any behind the scenes issues amongst the wrestlers/the promoter/the crowd so we try to enjoy the match as a whole. If the match is a momentum killer, we try to see if the next match can bring it back up again and build momentum towards the main event. From the CSE shows we've seen, most wrestlers put on a great performance (Case in point, Max Alexander vs Kwan Chang). But we'll do what Phil suggests (merch, bathrom, food break etc).
