Well, supermarkets are full of people in a hurry and screaming kids.
Libraries do have a kids section but the staff have time for you and they are generally much more pleasant. And there are U3A offerings and loads of hobbies.

No, didn't think so. It's baffling to me how rude people think it's acceptable to be when hiding behind a keyboard.
