Let's see if I get this straight.......come in on your own free time and volunteer to clean the aircraft and all you get is a t-shirt? Yea, right. Let's see if their CEO is first in line!
What I do beleive in are F.A's and F/O's picking up trash after a flight and before the next boarding. I've done this many times due to the lack of personnel at certain stations while the "ole bags" just on their butts and flap their lips on a cell phone.
