I never got tempted to take one because I always saw when the FAs cleared the meal, they would pick up the shakers separately and put them in a box on the trolley, presumably to make sure they had not been taken . . .I don't know how people could have taken them . . .

Anyways, I do not like taking stuff of the plane, I feel guilty and it is wrong. So I only take the Discovery mag, for reading later if I find interesting articles in it. And I am in my right to take it as it is a personal copy.
