It seems that passengers sometimes check out their brains and manners when they check in to a flight and board an airplane.
I normally take my shoes off and put on slippers when traveling in business class. It would not, however, never come to my mind to take my socks off as well and have everybody to look at and maybe smell them too.
Taking socks off is unfortunately not rare occurrence even on business class nowadays, but I cannot understand how some think that it would be appropriate towards fellow passengers? Cannot we agree that all passengers should keep their socks on during the flights, please?
