Today I noticed, on the WeChat wall of a girl who works as beergirl at Lovely food court, a photo with lots of rupiah and a USD $50 note with the caption "Today tips!"
I congratulated for the very good day and I asked who gave her USD $50 as tip (1 single note worth 650k rupiah!). She replied that a group of Korean tourists, first time in Batam, were very happy for the beers she served and gave her good tip. Good tip?? USD $50 for beers??
Now everyone understands why a 100k tip today does not lead so far as years ago during a massage session...
