That’s good that the police are concerned for your safety and have offered to give you & your crew a safe ride home! Yes, I would think that Armand does get this kind of interaction,
more because if the fact that he was under 21 when he was turned and not so much bc of the vampire beauty (from TVA):
I would never be anything but the seventeen-year-old boy you see now… [but] I am not a waif and never have been. I am a strong child.

Even if he looked “strong,” I’m an adult and it would concern me to see a 17 year old out in a bar late at night, too! I wouldn’t approach him myself, but I might worry that he’s in danger and alert a staff member. From my experience in many states in the US, it is a liability for a bar or club to have underage people even in their building, so most don’t even allow underage people in at all.
Armand probably has a big deck of fake ID’s that say he’s 21, though, and some people really do look younger than they are… combine that with his Mind Whammy abilities, so I’m sure he gets in wherever he wants.
