I wouldn't mind giving up peanuts.
I mind fat people hanging over into my space.
Bottom line...we all have different "minds."
Youi originally said you feel people would not mind giving up their peanuts if given a choice.
Thing is, in this case, that choice is to be taken away from them.
I am convinced that when I flew internationally in coach on the militarily dime, there was a regulation that specifically stated that the sweaty, 400lb German that didn’t bathe HAD to sit next to me. . .that or the 18-month old colicky baby that screamed for the entire flight.
