it depends on where u are. if your somewhere big like NYC, VEGAS, or MIAMI they will usually I.D. u at the door but other places that allow under 21 will usually let it slide for u to drink as long as u look hot. sad but true honeyy
Yes you will get carded. If you drink much they will cut you off. Don't touch the waitresses and you will be okay. Make eye contact with the people you want to dance with and they want to dance you it will be obvious. Leave with who you came in with.
