No, you'd be surprised. Those in the Indian discos are spending insane amounts on liquor. There are lots of beer towers being consumed. No idea how much they are, but they must be insanely priced if one standard beer is 300 baht. Not to mention, Indians apparently get charged 3-5 times more than other nationalities, if they take a girl from the disco, from what I've been told. 1k is standard for us foreigners but they have to pay 3k - 5k.
