In the good old days and the original Bangla road a drink was available 24/7 in bars. Any trouble was swiftly sorted and stopped by the locals. Tabs were the norm, I used to walk into my local bars,
to be given a bill, I would pay and begin again. Nothing was said and everyone was happy.
In those days it was mainly westerns and Aussie tourists.
I don't think there is an answer nowadays to the problems.
