I think the bottom line is that current can be scary, and not very much current can be very scary to a new diver. I can remember a very anxious dive when I was new, where I got frightened by current when the current was pushing me IN to shore. Water is very powerful, and getting in at the wrong time at a current-intensive site is at best an interesting experience. I called a dive once after less than three minutes, because we were in at the wrong time (not MY idea) and we had to wade a hundred yards or so to get back to our entry point.
We have a local site which is not known for being current sensitive, and which is extensively used for training, but every once in a while, it gets a quirky current that can be extremely strong. (We call it the "Redondo River".) It takes some experience to keep your wits about you, make use of all natural features you can to make headway, and keep your breathing under control.
If the dive shop apologized, it sounds as though either they did send these folks into the water at the wrong time, or they at least did not make it clear enough what the time parameters were. As a result, these guys got a sharp object lesson in the power of current. They may have learned things like: check with more than one source when you're asking for current information; check the site when you get there, to see if other divers are getting into the water (if they aren't, maybe they know something you don't); pay close attention to water movement, and head home BEFORE the current gets so strong you can't swim against it, and finally, that the surface often isn't the best place to be when you are fighting a current.
I hope the OP takes Cool Tech up on his offer. A lot of current-intensive sites are really fun to dive, because the water brings in nutrients that support a lot of life. If you pick the right time, these dives can be delightful, as a soft drift out and a soft drift back. But if Florida is anything like Puget Sound, you have to have a lot of information about the site to know just what the right time is.
