I’m trying to figure out what this would actually accomplish. When I drove the friendship boats, alcohol was not allowed on the boats out of the resorts, because of the different liquor licenses. (it was allowed on the boats inside Epcot though, of course.)
That’s all fine and dandy of course, however, I asked someone what they were drinking, and they said apple juice, or tea, or a virgin drink of some sort, we had to believe them. We weren’t allowed to question it or smell their drinks or anything (thank goodness). So assuming those same restrictions are in place, what good would a visual inspection of bottles do?
