I have a question

I sat in bus on my way to work and i usually put my feet on the seat(like take my shoes off and have my feet there only in socks) because i feel restrained in shoes if i wear them all day (i take any chance i can to get them off). So an older lady took a seat next to me and got real angry at me for it. Calling it disgusting and all that. I get that it's my fetish so i wouldn't mind anyone doing it but is it really that big of a deal? Would you get angry at me? (idc if you have a foot fetish or not im just curious about what yall think)
