I've never had an issue with any checkpoint at McCarren. What I have an issue with is stupid passengers who don't listen to the TSOs and hold up the lines. Here's an idea for you - maybe listen to the TSOs when they're talking, empty your f-ing pockets (COMPLETELY), take your water bottles or other stupid prohibited shit out of your bags, and put your damn laptops in a separate bin. I mean people, it's not that hard!!! If you don't like the process, buy a bus ticket!! Shut up and quit bitching!
