If someone asked me to remove shoes on entering their premises I would oblige.
However, unless they were wearing excessively muddy shoes, I wouldn't be so rude as to ask visitors or guests to remove theirs.
Why?......Simply because I was brought up in the days of lino, woodblock, quarry tiles, rugs etc, when homes were warm and welcoming. No-one sat or laid down on the floor That was for walking on, and could easily be cleaned. Even fitted carpets for those that could afford them were dark coloured or with pattern which wouldn't show minor stains, and would last for years.
They weren't pristine show houses with ridiculous cream coloured carpets and furniture, with owners desperate to keep up with the Jones's, or follow the latest 'must have' trend in the TV adverts or glossy magazine.
Just saying...😏
Rant over!
