If you want to get a picture with me and you ask me while we're in a crowd. HAVE YOUR CAMERA READY. Because odds are that your asking is going to spark other people asking. And suddenly there will be a line and I'll be making a beeline for an exit. If you're stopping me on my way out, that's fine, but you have to be ready for it. Know who is going to take the picture and make sure they're ready. Because it sometimes gets hairy in a crowd and I have to run away. So I can't be held up too long because it's only going to get crazier.
Thanks for your help.
