Of course this is the world famous B&H superstore in NYC. I have on quite a few occasions left more than a few dollars there. This picture shows only the high-end counter for D-SLRs and accessories. There are over 30 counter stations, and most of the time people are waiting in line to get called up to a postion (this was taken early in the morning so not too busy yet).
And this is only a small section of the store that also includes lighting, pro-audio, video, computers, even musical electronics, used equipment and lots more. And most of their business in done on-line!
