Feet clearly placed on a pocket containing items that a Pax would access using their hands would be worse IMO. Would you rub the soles of a strangers feet or shoes?
An unidentified photo taken in a public place posted on a public forum for discussion will not impact on anyone other than the person in the photo. Unless the subject of the photo is a member of the forum they cannot access the pic anyway IIRC.
I don't agree. I think a photo is a greater violation of common courtesy than feet on bulkheads.
And tell me, what about kids' feet? They stand on seat, armrests etc. Is that a problem too?
(and btw kids crawl on the floor where lots of feet are... so I'd suggest your argument that feet are the harbingers of microbial doom is probably inaccurate)
