I would say most people do wash their hands here, however I have seen everything. From people not washing them to people using the toilet, not washing them, and then sitting on the table for lunch.
My father would wash hands after petting a dog even, so I guess it's his germophobia that set the standard in my household.
* wear a mask in crowded environments where showing my face doesn't buy me anything (I don't wear one at work, but do at the grocery store or airport)
* wash hands before eating (or at least use hand sanitizer)
* grip the exit handle of the bathroom with a paper towel and dispose of it on exit
Not exactly double blind demonstrated but low cost and this year has been much better than last (which may also be due to my immune system having caught back up, too, so YMMV)
A good number of people do this in my city: when I go on public transit, I see a fair number of commuters with a hand sanitizer bottle clipped to their bag with a carabiner. Many people also have a bottle in their pockets or purse.
I would go out to lunch with mu coworkers and I would give out everyone wet wipes because I was the only one who had them, specifically for this.
No, we order first and then do it.
