It’s interesting to me that so many people assume by default that others have smelly feet. I guess we have all met the stereotypical sweaty guy at the local nerd convention. But in general, if your body produces a notable bad smell when you are not exercising and despite basic hygiene, there is probably something wrong.
If you walked through shit and dirt in your socks, sure.
But other than that? Do you really believe there is such a big difference between putting your feet wrapped in cloth on a seat and your ass wrapped in cloth? Do you think someone first puked on their feet, then put them on the seat and that’s how it got there? Do you really think the cushion is deep cleaned all day every day after the shift? Man, I got bad news for you.
