How do you wash your dishes in the US Eli?! Sorry, not being rude, just curious. I always wash mine like that. I always put leftover food in the fridge/freezer, but my in-laws will happily leave food in the pans they were cooked in overnight. They've never suffered any ill health as result, but I would certainly be more careful with a young child. As for no soap in bathrooms - that is disgusting, I've never come across that!
