Had a terrible experience as a wedding guest. I was carded at the start of cocktail hour (I'm 28) and didn't have my ID on me because I was carrying a small clutch. Although I was able to produce digital photos of both my passport and driver's license, I was forced to go back to my hotel (35 mins round trip) to get my ID. When I came back, I showed my ID to the manager but was still carded several more times throughout the evening. I get that the venue has to abide by the law, but I don't get why I was the only one carded or targeted in such a way when I returned. The staff seems confused and evidently unable to communicate with one another.
