On a flight back from Hawaii last year, I was sitting in F on UA in 1C. Before departure, the woman beside me proceeded to take off her crocs (classy, I know), put a plastic bag over her hand, and apply a medicated cream to her skanky feet. I do NOT like feet to begin with, so this was particularly horrific for me. The cream smelled so bad, and the FA saw the look of shock and awe on my face, and intervened.

She politely asked the lady if she would like to conduct this business in the lavatory, to which she replied no. Dear God. The FA told her that what she was doing was slightly inappropriate, and potentially bothersome to other passengers, as the cream stank. Long story short, lady got upset, and was convinced to move to the empty row 6 in F.

It amazes me that people cannot discern between activities that should be conducted in the bathroom/privacy of one's home or hotel room and activities that can appropriately be carried out in public without disgusting fellow members of society.
