Ok people here is my story. I went last night to my LDS in the DFW area of Texas for a PADI nitrox class. I wrote my check and went into the class room and filled out all the paperwork and then watched the nitrox video. When the video was over the owner of the shop started talking about the RDP and answering some questions I had.The conversation turned to computers I had already been there two hours.She Judy the owner of the shop asked me if I had a dive computer I said yes she then asked me what kind I replied I have a Suunuto Cobra and a Vytec. I told her I wanted to dive with two in case on a live aboard of or other expensive trip I wanted to cover my bases in case one or the other broke I would not loose any dive time.She understood and then asked do you mine telling me where you bought them and I responded that "you don't want to know." She said oh it's ok I said "on line" Well that was the wrong answer!!! She Judy said"I'll tell you what I am going to do I am going give your check back the class is over because you have no appriciation of a local dive shop and the services we provide and you care more about money than service". WOW my mouth hit the floor I have bought items from her shop and planned on taking other courses with them.Well she went off about black market no warranty or service and other things for about 3 or4 minutes. I was flabber gasted tried to talk to her but it was over. She gave me my check and I was booted out of my nitrox course.WOW!!!WOW!!! Well I do get good service from LP and that matters,and if she is not making enough money on classes raise your rate this is also something she threw at me. Well I did not see a sign posted any where in the shop that said " IF YOU DO NOT BUY ALL YOUR DIVE GEAR HERE YOU CANNOT TAKE CLASSES HERE" Hey she took my money. She will never see another penny!! I have taped my returned check to my monitor and when I am on the LP web page I will look at that check whilel I hit "ADD TO CART"
