NB to reader, this is an Andy Rooney rant, so read with appropriate caution while one's tongue is in one's cheek: Is it just me and how I was raised, but the very idea of walking around in a public space like an airport or on an airplane in bare feet is a completely alien concept to me, both on social civility and hygene grounds? Yet today, at LAX I noticed one woman walking down to the gate area in bare feet. Then in our F cabin, this same woman was brought up into the empty F bulkhead seat and after take off anchored her bare feet up against the wall for the whole 40-minutes to SFO! On my TK flight from IST-LAX yesterday I noticed several passengers had removed their shoes and socks and were bare footed, the only saving grace being they did use the slippers we were given for the flight. Still, it is not the most appealing sight to have a pair of exposed feet -- smelly or not -- in plain site on an airplane, and in particular in a premium class cabin!
