My info on those slots is that those 80% is the average payout for a bank of machines or even for all machines of a company/casino. Compared to up to 98% in some casinos 80% is really low.
Avery Cardoza writes in one of his books that you should avoid those airport-slots (same as slots in waiting lines for buffets or at restrooms...) as hell, because they are by far tighter than others.
