Kind of strange experience the last 2 times I was in Vegas. I'm almost 43 yrs old but I've been told I could pass for late 20s or early 30s.
Anyway, both visits, I've been carded at almost every casino when I sat down at a table with my friends or stood right behind my friends at a table. My friends are in their mid to late 30s and they could pass for mid to late 20s (we got lucky with the youth looking gene). Some of them (not all) also got carded.
In any case, I don't understand why I personally am getting carded, other than I look SO young that the dealer needs to ask. I definitely look older than my friends but the group as a whole does look young (compared to our real ages)
Are casinos like liquor stores where if you look younger than 30, they need to check ID or are they just making sure we aren't a band of card counters trying to take their money? I'm hoping it's the former and not the latter :)
