It's been a while since I've written a Yelp review, and after a week in Vegas, the service that impressed me most was the TSA. They were actually friendly! In Seattle, they are really strict that you must let them tell you what line to get in. Here I was, waiting for the guy to direct me and he told me "Roll the dice... it's Vegas, baby!"
They were also super chill a few years ago when I lost my wallet and had to board without my driver's license.
I'm not a big TSA fan in general, but maybe if we could clone this team and put them in all airports, it wouldn't be so bad.
