I had that happen once in my three years in the fleet and they didn’t open them for us (long time ago). We did have kegs & BBQ on the pier in GITMO once, too (“pigs on the pier”). I was in when they were just starting a/the tobacco ban on the ship. You could smoke them, but you couldn’t buy them . It created an excellent black market opportunity for entrepreneurs onboard. Last fun fact - my ship was catered by Krispy Kreme donuts every morning when we were in port - long, long before they were a nationwide brand.
