Be aware!!! We do not have the habit of asking the price of bottled water in restaurants ...
Today these leeches Butlers Chocolate Cafe, Bangladesh charged my wife BDT 78 for one miserable 500 ml MUM branded bottled water (won't complain if that was Evian).
When asked why the price is so high the reply was "We have bought that and now we can resell that at whatever cost we want." My wife was with her friends (all ladies) and couldn't pick up a fight. But anyone who likes to value their money please be aware and ask for the price of every item (I once asked if the tooth-picks are free or not) ... Stay happy!
