Their design, while deemed diabolical by some, is a marvel of efficiency.
Anyway, having to powder her nose during the leg of her trip between Lima and Dallas, it suddenly hit Paula: the airplane facility was nicer than any public bathroom she had seen in Peru!
It had, in no particular order, but to her increasing amazement, a) a toilet seat (not considered a standard feature down here), b) toilet paper (it is routinely 'liberated'), c) something called paper towels, which I vaguely remember from a previous life, d) warm, flowing water (!), e) soap, and f) a door, and it even closed! And locked! Dude!
We hope that you have better luck than we have when the need arises.
Dave and Paula
