Request: which restaurants, beach bars don't charge SC?

There's alot of new information about service charges lately. I too noticed at Da Waterhole, beers at bar - no service charge however beers and burger (fries $$extra) at bar, the entire tab has a service charge added. Ps wifi only active for 1hr/day. After that there's a surcharge.

On the other hand, Kalatua beach bar on Mullet Beach doesn't charge service charge for drinks, but also keeps the change on $5.50 beer (so effectively a SC). And this after you have to walk to back of house to pay (not server or bartender but pay at a separate booth).

Now, I wonder which beach bars/restos don't charge service charge?

Note: Surely, I am not the only one interested in supporting these establishments?

Thoughts/comments/advise?
