I pretty much always buy something, every time I walk into a B&M.. regardless of my purpose for being there..
Not sure if there is really any etiquette or rule on something like this.. Im sure a lot of people that arent regular smokers walk in and walk out every day without picking anything up....
The only exception for me is when I go to the lounge/club that I belong to, that happens to be inside a B&M.. I will sometimes go there and not buy anything that particular day.. but my locker is stocked with sticks that I have purchased there previously that I smoke while I am there... so I dont really feel bad about that (they got my money.. they just got it the last time I was there instead of this time type thing..)...
