This discussion as with most discussions here lately seems to focus on the American perspective. A focus which glosses over the likelihood that the majority of foreigners of all other nationalities outnumbers Americans - Are there enough American sports fans to support a US style sports bar year round? Those who enjoy sports come from many countries but not with the same level of interest that is demonstrated by US fans for US sports. I don't see locals patronizing gringo bars in great numbers nor do I see those not interested in sports inhabiting these places just for the ambiance.
Excepting the Super Bowl and the other major championships I would be surprised if there is sufficient interest in putting down roots in a bar to stare at a TV screen week after week as we progress through the various sports seasons. If I wish to watch a sporting event, I am more likely to do so at home, where I can surround myself with my friends (if I so choose), the costs of refreshments and snacks is much more economical and where I can see and hear the TV much better than I can over the exuberance or protestations of someone who has misplaced their sense of public decorum.
I wouldn't think there is enough of a fan base locally to support a true sports bar year round in this neck of the woods based on an arbitrary percentage of the total available population to do so. The chances of someone coming from Puerto Plata or from the east to Sosua/Cabarete to watch an average event on TV and socialize, I would think I should be able to count on one hand. The vast majority won't sit and drink for three hours and then drive home, so the majority of the clientele for this type of establishment needs to be local, within walking or taxi distance. My general rule, if there is more than one TV tuned to a sports channel, I go elsewhere. I'm not into sports in that way and prefer to engage with people whose attention doesn't dart from me to a TV and back again. Something akin to someone picking up their phone mid sentence to see what useless tweet someone they have never met has just sent out.
Sure different strokes for different folks, but a decent marketing study would clearly show that there is not enough "die hard" patrons to support this type of venture day after day with any sort of profitable consistency. On a beach strip where the pricing is similar and the choice of atmospheres diverse, It must be a hard row to hoe to entice a critical mass of patrons to stop and consume enough to keep a specialty establishment profitable yet there needs to be something to keep the chairs full. I don't think any of the owners are banking profits that far exceed expenses or are sufficient to offer a significant return to investors for their start up capital. Just scraping by can be a precarious situation to be in if market conditions suddenly change.
It seems to me that that there are only so many business establishments of any kind that the population is able to support, therefore, any number over and above this number will not succeed or will drive the less enticing establishments out of business in a never ending game of "snare the gringo and his wallet".
I assume that part of the motivation for the original sale of O'Shay's was that the profit margin was not large enough to entice that owner to keep going. The new owner, likewise was not able to capture enough clients to come to the conclusion that avoiding foreclosure was in their best interest. We don't have to go back and forth and round and round to see that neither owner was able to completely realize their goals and this probably has lots to do with the number of consumer choices readily available on that beach and the fact that there was nothing unique and in demand on offer - the one pie is being cut into X number of slices each day and all things being equal, that pie is not big enough to satisfy the appetites of all those establishments all the time and forever more.
This establishment failed, another will fail in due course, something will replace each one eventually. If nothing else changes, this cycle on Cabarete Beach will repeat itself endlessly.
