SPANDEX!...IT's GOTTA BE SPANDEX!!!...........
ROTFL!
I have to wear socks though. Does anyone ever clean the floors around the security areas? They are so FILTHY and you have to walk through that dirt to find a chair to put your shoes back on.
If you have flipflops, your barefeet are on that filth.
I mean FILTH, DIRT, nastiness. ICK!
