This is such a weird mentality to me. You don’t get compensated for waiting in line either. Would you really rather stand in line than do self-checkout? Even if it were faster? Doesn’t everyone always say “time is money?” Then you’d be robbing yourself if you don’t pick the fastest option.

Edit: I always pick the fastest option. The less time spent shopping, the better. But then, I’ve never really had bad experiences with self-checkout, so I’m sure I’m a bit biased.
