I for one want a clean cabin, I don't want to be siting in someone else's squallor! But then again I am also the sort of person who leaves my little space the same way that I found it!
So, as a minimum, what would you prefer to have been done when you get to your seat...do you look at things like carpet vacummed, no rubbish in seat pockets, seatbelts crossed?
You have pointed out the bare minimums! I also expect the tray table and window to be cleaned, chewy removed from under the seats and if required the headrest cover replaced! There was a time, not that long ago when this was the standard...
PS: You may ask how I know that there is chewy under the seat, simple really, every flight I check to make sure that my life jacket is where it should be! Yuck!!!
