When I visited the States, and New York in particular, last year I really wanted to go to B&H, so I went there on a saturday afternoon and was puzzled why it was closed, until I came back next day and I set one foot in side it all became clear in an instant. Really cool store, especially their way of getting your stuff to check out.
But very friendly and helpful people, even asked me if I wanted a full pack of fuji 400H because it's 10 bucks a roll...
I now work across the border, in Antwerp, where there is a large jewish community, so I'm a bit more acquainted to their customs. Still a funny sight when it rains tough, they use shower caps to keep their hats dry!
