I would think it is a fine line the LGS must walk. The other extreme is when you walk onto a new car dealership. You will have someone in your face before you shut the car door. You might not even have to open it before someone is bombarding you with whether you want to finance or pay cash. . .
I frequent a gunshop that will greet me and ask if there is anything I would like to look at. If I am just browsing, they will just leave me alone.
