So I'm actually down in Costa Rica right now. We got in a few days ago after spending a week in Cabo San Lucas....and by the way, the water there was COLD. My dive watch said 57 degrees F.
Anyway, the first day we got here we drove into Tamarindo to find the dive shop. We were still a bit tired from the travel but were nevertheless excited to find the dive shop and get our week in Costa Rica started on the right foot. The GPS unit got us there just fine and we went in to fill out our forms and make sure we could dive with them on July 2nd as I had requested in a few of the e-mails I had sent them prior to our arrival. I'm not sure of her name, but we were greated pretty coldly by an Italian women in the shop. The entire time we were there, I felt as if we were bothering her or taking up her time. She answered any questions we had with very short, abrupt replies and when someone else walked into the dive shop, she ignored us completely. She wanted us to prepay for the dives and we couldn't b/c we didn't have the money on us at the time. She told us we had to prepay the next day or we couldn't dive with them so we'd have to stop by tomorrow. I suppose I was taken back a bit more than usual by her abrupt manner just given that everyone we had encountered in the country seemed so laid back, friendly, and helpful. In any event, it was enough to put me off from diving with them completely.
The next day (today as I write this) we looked for, and found, a new dive shop in Playa Flamingo. The shop is called Aqua Center and they were far more welcoming than Agua Rica. We ended up signing with them and will be heading out for a pair of dives tomorrow.
Later on, we actually stopped back by Agua Rica just to be courteous and let them know that we wouldn't be diving with them after all. Before I could even tell the lady we were canceling, she was just as rude and abrupt as she had been the first day we'd met her. I'd like to think I caught her on a bad day the first time around, but two times means it's just her personality. Anyway, when I told her we were cancelling, she almost seemed happy as if to say "two less customers to deal with".
I couldn't tell you if our new dive shop, Aqua Center, is good or not, but I'll be sure to let you know. My best advice so far to anyone visiting Tamarindo soon; make Agua Rica your second or third choice in a dive shop, particularly if you value a friendly staff.
