Wouldn’t affect me, minibars are total ripoffs.
I look in the fridge for stuff I want, hop a bus to the mercado and stock up for less than a third of the minibar charge, plus some extras.
Set the minibar stuff aside & put my stash in it.
Too bad for these victims but it does sound like serial murder. And then that sports star is shot in the back in a bar. DomRep doesn’t sound too safe and their minister for tourism is sweating bullets on TV.
You may or may not want to use it, but it should not be deadly to use a drink from the minibar.
