I don’t see TSA making her do it. In fact the clip shows one of the TSOs helps clean up the spilled water.
Are you referring to the crotch-grabbing guard with the grey hair?
She had already wiped the floor once before crotch-grabber radios for paper towels. While waiting for the paper towels, he sat there for several minutes while people walked by, showing no apparent concern for a safety hazard. It wasn't until later that he started directing traffic around the area.
He came across as an officious little prick, IMO. I'm not convinced that releasing this video was a smart move on the part of the TSA.
