People to avoid, Athens
I am happy to say I avoided scams due to common sense and the tips on this board. Thanks to all. That Francisco guy definitely approached me a few days ago near the acropolis. He was posing as an Italian tourist. Italy jersey, glasses, fanny pack, etc... He kept trying to talk to me and followed me a bit, trying to engage me and find out information about me. Just ignore him, and if he persists tell him you don't want to talk to him, and if necessary, you will call the police. He will slink back in the gutter from whence he came :) strangers who are determined to speak with you want something. Often either to manipulate you or distract you while someone else releives you of your wallet. Normal people just aren't that interested in strangers. Also, use a money belt, and carry a "dummy wallet" with nothing important in it as a decoy. If you keep your eyes open, and take precautions, you will have a great time. And don't let this scare you from talking to people! Just be cautious, and if you are asked to go somewhere, suggest an alternate arrangement in surroundings you trust. If it is a normal person, odds are they will acquiesce, or meet up with you later on.
I was actually looking for a bar in Athens a couple of years ago when an old guy came up to me on the street and told me to check out the bar he was heading to, which just happened to be the Hollywood bar. I had 2 glasses of bourbon and coke and I got charged $150 Euro!! A huge bouncer appeared from out the back to block the exit ensuring I would pay the full amount before I could leave.
I walked back and found the bar the next day:
And I found the old guy trying to hussle more tourists: http://www.igeekden.com/wp-content/uploads/2014/06/Greece-681.jpg
