have a public restroom?

seriously, I am curious. One LBS I have been to does, two I am not sure about, and one of them does not.

I was surprised that the latter one suggested I go down a few blocks to a restaurant if I needed to use a restroom, but if I have to go that far, I'm not likely to be back all that soon. Granted, the number of times I've needed to use a restroom while at a LBS hasn't been all that high, but I was thinking of taking my wife bike shopping at the LBS that doesn't have a restroom, but since we'd have the 3 yo in tow, he at least would probably end up demanding to go potty....
