Re: social proofing
Its really simple. Just compliment the hell out of them. Especially the guys. Avoid being a suck up of course, but it'll loosen them up and even tease them once they warm up to you. Spend just a couple of min then eject. You can go back to them later and open another set the same way. Afterwards you can choose your target, but this is how you would build social proof in a place you haven't been to before.
