In BA there was/is a strict management policy that says staff on duty or leisure travel must refuse the offer of wash bags, amenities etc.
I was fortunate to travel on Concorde, which I'm sure you are aware, gave quite valuable gifts to customers on board.
Seated in front of me were two well known BA Directors when the wash bag and gifts were distributed by crew not only did they take them but actually asked the crew if they could have two each!
A classic case of 'do as I say not as I do'.
