Could not have said that better myself, Dan 
A lot has to be said for the approach though. If some big thing from the sky poked me in the side when I was sunning by the swimming pool (waterdish), I'd most likely bite too.
The times I've been bitten is when I've been lazy and moved to quickly/from above -- they get spooked...and well, if they're grumpy and don't want to be messed with, that'll do it fair and square. Can't blame them really, its instinctive defense.
As a kid I had this one Anole that was so territorial of the water dish...every time I removed it for cleaning and refilling he would flare his red throat and latch on to my pinkie finger. He wouldn't let go until I put the dish back -- and try washing a water dish with an anole stuck on your finger! LOL, luckily Anoles don't hurt when they bite.
