3.) This situation is fairly unusual, so AA doesn't feel compelled to a.) pay their cleaning staff more, b.) re-train their cleaning staff, and/or c.) provide more time for their staff to do a more thorough job.
4.) Similar situations arise with some frequency, but AA feels there hasn't been enough complaints to warrant trying to fix the problem.

Any one - or a combination - of the above could apply to your predicament; the only thing you can do is to complain more to AA or take your complaints to a more receptive ear.
