I hope not, but that may become more common. I like Gentleman Jack. A few months back half way through the cruise they were out of it. Regular Jack Daniels? No. Wild Turkey? No. All they had was some brand I never heard of. They apparently did restock at the next port.
That was the first time in decades of sailing I was on a ship that ran out. A while after we got back someone posted on here about their not having something else. I think it was on the Vista and someone responded that the delivery truck had been stuck in Galveston traffic.
So, just like the quality of food - the raw ingredients like beef - have gone down to save costs or, like bacon, become rationed, I would not be surprised if the quality of alcohol goes down.
Hope I'm wrong.
