It was a B'day Party!

Birthday party leaves me surprised, this had never happened to me before. But, it was really something different, different enough to surprise any Indian atleast. With a knowledge that one of our colleague has birthday today and wants us to be there in a bar in city-center (nothing odd if you know you are in west) we all went there after office. Party was good and we enjoyed our drinks and company of each-other for the evening but then it was time to go. Time to go but the surprise to come, and the surprise of, the way it was all ending. Everyone, took out his wallet and started paying for their drinks, n I was looking it all amazed and stunned..completely clueless, "whats this, it was a party by someone only sometime back!!!". Anyway, me too paid and walked out, but later only come to know that, this is the way they party...u have to choose your drinks, have it...n then pay for your drinks and leave!
