As best I know, Bill had a very curious backstory. The Aqua Safari business was started by a relative and then turned over to a young Bill, who was a US Citizen at the time. Early on, he was in the US and trying to return to Cozumel but there was a big problem with immigration and he had to give up his US citizen ship to reenter Mexico where his business was...at least that is as the story goes. Then Dave Dillehay comes along with Aldora, and not only does he raise the bar of service, but retained his US citizenship. Then the big three were Dive Paradise, Aqua Safari and Aldora.
As best I recall he hated my guts and was terribly rude every chance he got. Eventually he accepted that I was going to be a competitor and in later years was occasionally polite to me and smiled. After he sold Aqua Safari he became almost genial as I was no longer a competitor. I held no ill will then nor I do now.
I still have no idea for the cause of his demise, but maybe some other locals can fill us all in.
