RE: What would you change...
FWIW, I would try to avoid the loitering, club type atmosphere that many pro shop have. Seems like the same guys are always just hanging around talking, but not really doing anything (shopowner included). Whenever I come in I feel like an outsider (I get weird looks because I am breaking something up I guess) because I ussually come in just to do my business then leave. To tell you the truth, I don't like going there, and avoid it if I can.
I would just try to treat each customer evenly and fairly. Other physical things such as shooting broadheads are secondary to me cause I can do that at home.
Also, try not to be biased toward products that you personally like.
JMHO.
