Just recently, I waited an hour to board an AA (regional) flight at ORD because a kid threw up in the jetway. The reason it took so long... nobody would come clean it. The cleaning company refused. When somebody from the cleaning company was finally forced to come out, he put paper towels over the puke and called it good. The Captain (who relayed the story to me in the JS) put his foot down at this half measure and good for him. The cleaner himself would not walk over his own work but expected the passengers to step / roll their bags over it.

My point? I don't think it has anything to do with Spirit. It's the same workers who half as$ clean the cabins, show up 20 minutes late with wheelchairs, etc. It's and Airport problem, not ours.
