Brits, what do you wear when dressing casually?

Those aren’t really British rules - they’re big city rules. New Yorkers would probably tell you something very similar.

Yeah, you’re never going to stop this from happening so long as there are large numbers of small town folks visiting big cities. You’d have to start teaching “comportment in the big city” lessons from kindergarten to make any appreciable change.

Exactly, big city rules/public transit are the same everywhere. As a Chicagoan, I fit in fine. The same rules apply in Chicago, DC, and London. But, there will always be people standing on the right on escalators or walking 4 abreast while pushing a double stroller. They’ll always be people who don’t let you off the train or elevator first before getting on. And, they’ll always be those cursed selfie sticks!

The slight difference is that in British cities the pavements tend to be much narrower so it’s easier to cause problems.
