I still find that surprising, do you have stats that you can link?
The smell of alcohol alone is very distinctive, so I don’t think most would need to even taste it to know it’s AF. It might fool them if it’s served in an area with a lot of alcoholic drinks nearby, but even then a quick sniff should make it plainly obvious to me and, I assume, most people. I don’t have a particularly keen sense of smell (my wife smells a lot of stuff I don’t notice), so I don’t think I’m special here.
