@adron oh, I get it now. I thought you're asking about climbing. You can change mine to "kind of" because putting legs on the table was considered to be a capitalist / Western thing in soviet union, which got engraved into my family during the occupation.
I think it was specifically for tables and was modesty-centric.
@jonn oh yeah, not really a capitalist/western thing either. In general society in the USA at least is very against having people put their feet/shoes on chairs/coffee tables/etc. It's considered rude af. However it seems, among those of poverty it's a thing you just do, for a host of reasons, often though with young people it's just a lack of awareness or caring.
It always kind of just bothers me out of the fact that, it's very hard to construe it as anything but rude and disrespectful.
