"Protection Fee" for the bike
We then went to Thac Bac (Silver Waterfall). There were a lot of stalls lined up beside the entrance to waterfall, and they were not embarassed to ask us to park our motorcycle at their stall. The treat is, you have to buy something from them so that they will look after the bike for you. They all seemed know the rules, as most guide books mention about it. Even the guy who borrowed us the Honda bike suggested us to buy something for about VND 2,000, but we ended up paying much more than that.
We decided to buy a pork skewer from this stands. We initially just want tried 1 pork skewer for VND 5,000. But she just prepared as many as she could and pushed it to us. Ended up I ate 2 pork skewers and 1 rice covered in the bamboo for VND 14,000. Expensive!
