that's sure thing but khaolakguy quoted belowi is right
few years ago I had similar heats and since it ended well , there's story:
on my way to OTHER bar I stopped to hand over small tip (50 or 100) , smiled and continued my way. Upon return I was greeted with smile on approach so slipped another small tip , smiled even more broadly and went away.
day or two later - repeat but this time I was greeted with 'how are you ? " on my way , still to a different bar. Returning 1-2 hrs later I was met with extended hand , gave another tip and was rewarded with " one day we need to have a beer together" . It did not happen because it was my last day but I was back few weeks later and was greeted with smile and reminder about the beer. This time I discretely whispered "when?" , 'I will let you know " was the answer. So I ordered a meal , half way through the meal asked him if he wants a beer, he did. It was enough to be informed that his day of was Sunday so I suggest ' lets meet on Sunday. Which lead to exchanging Line.
When I had Line things went fast so we meet over beer in place by my hotel, I invited him for a dinner which was enough to hear suggestion " why we don t buy some beers at 7/11 and drink in your room to save money" . It was like getting phone from lottery office ' you just won 1.7 million ' or something . In the room we both behaved for a first round but when we opened second slowly but surely , not that slowly but certainly very surely things moved toward , how to say it , less formal atmosphere.
In short, smile ensuring I'm interested with a little help of money steered guy to right direction without me being pushy or offensive which would certainly put him off.
