"in fact one trip - a new guy was swirling and grinning in front of my beach chair
one of the regulars shouted out to him "she don't mess with no beach boys" "

I've had similar experiences through the years. New guy on the beach tries to get my attention/gain my favor. One of the "old hands" nudges, talks in his ear... end of that hustle because the more seasoned guy just gave him the "she don't mess with no beach boys" message. Pretty funny to watch. Guy getting his moves on then, act over. Good entertainment though.
