Not at all. In fact, I'd be willing to pay a fee to use it, provided it was reasonable. A buck or two perhaps.

Do airports owe us a rest room facility in reasonable proximity to each set of gates? No, but it sure is nice that many do.

Again, I like that Southwest offers outlets at their gates. Among other good reasons, that is why they continue to get more and more of my business. Just wish they had more destinations.
