Two things about the men's room about at ART - there are plenty of back issues of US' inflight mag on the toilet tank to keep you occupied while nature takes its course, and space constraints dictate that the only urinal is placed not two feet from the sink, and angled in such a way that the person using it is in full view of the person using the sink when they look in the mirror. Great for exhibitionists!
Regarding the TSA, of the eight people that boarded with me at ART, I was the only one who didn't get the full treatment. Might have been something to do with my now-automatic adherence to TSA checkpoint rules.
As for the cab, I didn't use it, but I was talking to two elderly local ladies who were waiting for my flight who described the cabbie exactly as someone else in this thread did - fat, smelly and always blasting country music.
