I'll start with coffee shops, chains in particular - if it's past 9am, tables that are free are covered in empty cups and dirty bags from previous customers, surface wet, soiled, chairs covered in stains and crumbs - and this remains like this till end of day.
Toilets, even in nice restaurants are smelly, sinks full of hair, water (or worse) stains, at best you can expect to find the toilet seat wiped - maybe. But beneath it you'd find urine and feces weeks old, the actual toilet bowl stained, at best you'd expect the clean bowl but a heavy build-up under the rim. Floors, walls - that seems to be cleaned only when the establishment is first open.
And people don't seem to mind, people don't seem to clean behind themselves either...
The only exception are 5 star hotels really, if you can even call that a public space.
I am mentioning this as a heavy contrast to some parts of Europe for example, where tables get cleaned behind every customer even in chains such as McDonald's or Starbucks - these actually look inviting, clean and airy. Toilets are airy, clean and properly washed every few hours (not just checked for dead bodies and a tick on the schedule hanging on the door). Yes, you can find a filthy toiled but it would be fresh stain clearly coming from a person without any manners visiting in the last hour or two post last clean.
Now, the reason why I am writing now after years living here and thinking that it's just simply a different hygene standard people got used to.
Few weeks ago, through work I found myself in an establishment akin to private club. It is a public space in the sense it is busy and frequently visited (although by a selected group of members), and after queuing for a toilet I found myself in a public toilet that was actually proper clean.
So I realised - the hygene levels here are very high, it's just that it only applies to a selected group of people - while the assumption is that your average person should be completely fine with sitting on a stained chair or feeling like they are walking through a sewage if they decide to visit a toilet during their meal in a restaurant.
How, why and when has this become acceptable?
