I done the deal, all went fine. Kinda hard to count £1000 in a very public place, was more worried someone else was going to mug me, not to mention it looked like a drug deal.
I don't know why but once I had a same feeling. Never used drugs so it must be because of movies

First confirmation is enough, no way back so no need to wait all six.
Don't go alone if it's bigger amount.
