Teens never want to be seen with their parents in public, especially if they are with their friends. They will totally ignore you.
One time my friend and I went to the local movie, stood in line for our tickets. Lo and behold, daughter and her friends got in line. She came up and joined me, wanting me to purchase her ticket.
I bought only one, when she said something, I said " I dont purchase tickets for kids I don't know", and walked in with my friend, her jaw dropped.
