I think unfortunately you're right with your thoughts about the perception, but this leads to very misguided customer happiness management crap. Since it's well known that cashiers (especially at grocery stores, but in most countries this is a general thing) are not that well paid while the work is all about speed and efficency (aside all those unpaid overtimes, at least in German discounters), it tells much about prevalent work ethics. It should be "Why on earth should those people stand while doing this monotonous work everybody needs to get done?" instead of "Why are those lazy people are allowed to sit while taking my hard earned money?" But I doesn't think that those customer happiness advocates do care much about those trivial considerations.
