I didn't think so until I moved abroad, now I do but only for a few things as on the whole most people are hygienic. Now I live in country where they are obsessed with cleaning and unfortunately (and incorrectly) the stereotype Brit is thought of as someone with bad teeth who eats badly and isn't very clean ( based on carpets in bathrooms) and people sitting on publish toilet seats!
Mostly I've noticed it around clothes and eating. We use a tablecloth (or placemats) and napkins for every meal, in the UK it never occured to me to do this, but in my adopted county it is unheard of and it feels strange not to clean your mouth during eating. Same goes for toothpicks, I can' t recall ever seeing then on tables in the UK, but instead people using their finger to pick out food that's stuck in their teeth! Eating sandwiches, burgers etc, everyone here wraps a napkin around them and never touches the food with their hands.
Washing dishes, I used to leave the soap on them, my MIL watched me in horror the very first time I washed dishes and didn't rinse them! I also noticed everyone here rinses them before putting them in the dishwasher, which I think is not recommended.
I've learned ( but not necessarily agree with everything) that clothes that have been worn even once like jeans should never folded and put back in the wardrobe/drawer with clean clothes. Men should always wear a t-shirt under shirts ( and this is a hot country!) You should never sit in or on your bed in clothes that you've worn outside (fear of contamination!) and shoes should never be worn in the house. The sink cooker and bathroom should be cleaned daily ( sod that I work 10 hours days and really don't have time) and hair should never be dried anywhere except the bathroom (we have plugs in our bathrooms as it's where we have our washing machines). Children should always be clean and if any food is on them, clothes must be changed and photo should never put of social media of children with food around their mouths!! You should shower before entering a public pools and swimming hats are law even with a shaved head. I don't think I ever saw colleagues in the UK lining up outside the bathroom after lunch to clear their teeth either. oh and the lack of bidets in the UK is a whole other conversation.
I could go on, but I think where I live some things are a bit extreme too!
Oh masks are mandatory outdoors where I live, so I use a new disposable one every day.
