It could be. The real point is that N is totally unnecessary for a
coffee shop. Even B is more than good enough when there's no security.
If I were responsible for the coffee shop, I'd recommend WPA Enterprise
with a RADIUS server, with a small printer to print out time limited
authentication credentials for paying patrons, which would essentially
mean going with G over B. That way all connections would be isolated
and secure. I'd also recommend a high-grade router with traffic shaping
so no one patron could hog all the bandwidth, and blocking of
filesharing.

Correct.

Some places do just that, but it can often be defeated with a high-gain
antenna. Others use authentication to keep out the leeches, which is
much more effective.
