Well for one, dive shops need to support their customers.what I mean is their`s lots of shops that I have been in where the people act like they are doing you a favor by talking to ya. and that`s non supportive of the upbeat and excited mood that I was in. now , I felt like I just walked out of a mourge and my feelgood dreamboat just got turned into a shipwreck on it`s way to the bottom due to that shops torpedo of depression, so I have copped the attitude of just using shops for what ever I have to.However there has been three shops that I have enjoyed visiting and will continue to business with them.My point is, sometimes attitude can make you or break you. So support that customers positive side.
