@ Charlotte Douglas Airport in North Carolina: Despite some long layovers, I think this is my favorite airport. I love the rocking chairs and big windows. Not sure what to make of the ladies’ rooms though. Each bathroom has a designated attendant who keeps things clean, greets you upon entry, provides complementary Listerine among other items, and prominently displays a tip jar. What if I don’t want her mouthwash or other goodies? Just a toilet and sink. Should I tip? Sometimes I feel passengers are being taken advantage of—-just a little bit—-and getting guilt tripped into dropping some dollars. Is this a remnant of old world etiquette and goodwill or a plot to further extort travelers . . . after they’ve dropped $15 on a stale sandwich?
