It works if you are well dressed and are attractive to the person you are approaching.  Otherwise it goes about as well as you would expect.

Nah. This is just to talk, not to date. The problem is a lot of guys focus SO MUCH on finding a date that they make it weird or creepy. Just be normal and strike up a convo. Even if the woman isn't attractive to you or older than you prefer or whatever.
