At pycon last week or so in Salt Lake City, I saw the bars are religious about scanning your id before you walk in. Every place that has a bar does it.
There's also restricted drink pours, and you must finish one drink before getting another. So like you can't order a double whiskey, nor can you order a regular martini -- although small ones are okay.
There’s also weird things about liquor licenses for “bars” in Utah. If you ever go back, ask any bar for their food menu and they’ll almost certainly bring one out. I’ve been told by a number of bartenders that only “restaurants” can get a liquor license (I’m sure that’s simplified). Then the culture of many such “restaurants” is indistinguishable from the culture of a bar.
The ID scanning is because of a local law, pretty blatantly intended to target ~bar~ “restaurant” hoppers, which was naturally only controversial with members of drinking culture. Sometimes I go to lunch at a local “bar” which has to scan my ID as soon as I walk in the door regardless of what I plan to order.
