I like this thread because it has brought Smith out of hiding.
My wife and I and another couple did a similar, 'drink stealing' thing while staying at the Riu complex in Punta Cana in 2009. There were five Riu's all grouped together. We were staying at one of the three 'regular' Riu's and were encouraged by the management to visit, drink and dine the other two. However, there were two Riu Palace's and we were told we couldn't enter those, so of course . . .
One morning we decided to tour all the swimming pools at all five of the Rius and get a drink and take photos at each one of them. There were 14 pools in all, including the reflecting pools and fountains in front of their 'Grande Palace Riu'. The Palaces were the last pools were visited, so we had all consumed at least 10 drinks by the time we got there. We did manage to get 'free' cocktails at the Palaces, but it took some subterfuge - they wore bracelets at the Palaces. Of course the girls just walked up to the bar flashed big smiles and pushed out their chests - and they got their drinks. Me and the other guy had to work a little harder.
We accomplished our mission and had a fun time (even though we weren't in Negril) and I think the Riu survived our 'drink pilferring'.
The photo is of me and my S.O. in the Palace fountain pool, the last one, after our 14+ drinks.
FredStripe is right - those illegal drinks taste soooo gooood!
