Well, I'm astonished! I've never seen anyone in a shop in their pyjamas, although I know plenty people who will put jeans and a sweater over the top if they are just going to the local shop. I'm going to give it a try and see what happens, though think I'll wait for spring.
Pajamas are the least of our worries in the library. We don't have to worry about blocking the porn sites because some of the women come in dressed with just enough on not to get arrested. (Joke folks, we are required by law to have filters on the Internet computers. Thank Al Gore for that one.)
I only wear shoes when I go out. When you come to my home the first thing you see is a pile of shoes by the door because everyone takes them off when they enter. Not required, we just prefer barefoot.
That said, I would never put my barefeet on a booth bench or chair in a restaurant. My husband has a foot fungus from Vietnam that comes back regularly. Would you want to put your barefoot on a bench where he had his barefoot?
The saying "No Shoes, No Shirt, No Service" does not mean that after you enter an establishment you can begin shedding your attire. Appropriate clothing applies to the entire ensemble for the entire public outing. If your feet hurt make a mental note to not wear those shoes again. If your flip flops flip onto the floor it would be best to slide it back onto your foot rather than sitting cross-legged.
I too never wear shoes except when I have to be in public and then I wear flip flops, even in winter if I can get away with it. I have no problem with elbows on tables, talking with food in the mouth or bare feet at the table because I NEVER eat out.
I have seen what sometimes goes on in kitchens and to food. It can be dropped on the floor and put back on plates, people spitting in it after it had been returned with a complaint then sent back out. Nasty things, nasty people!
As for cutlery and crockery well, unless I know I have washed and rinsed it, I don't eat off of it!
Sounds a bit OCD but I am not, just particular about my food and how it is cooked and presented.
I also save a fortune and I am also a black sheep!
