We had to park the scooter across this river from the caves due to the only bridge being washed away some time ago. The only way across the river (which is about 15 metres in width) was this dude with his boat. When we arrived and he first took us across, he demanded 20,000 Kip ($2.50) - again a very unreasonable amount. I gave him 10, he then wanted 10 from each of us, and he didn't get it. On the way back, he this time asked for 10 hehe, but I refused to give him anything which really fucked him off. To put this into perspective, our guide gave us a couple hours of his time, took us through the caves, pointed out bits and pieces, took photos of us etc., and 20,000 Kip is considered a reasonable payment in return for that. This prick however gave us two minutes of his time, and twice took us all of 15 metres across a river that we could've just swam across if we felt so inclined - 20,000 Kip (10 before and 10 now) is definitely an unreasonable ask for that. As we walked away he followed closely, yelling at us in Lao hehe. I stopped, turned and reiterated that we had made sufficient payment already, and so he threw his fists up and just stood there as if challenging me to a fight over it hahaha! So there we were, standing beside a river in middle-of-nowhere Laos, and this little Lao man of maybe 160cm in height (a little over 5ft) was wanting to throw down with me! I gotta tell ya, I love my life ;) Anyway, as he stood there, I just smiled, turned and continued walking towards our scooter. He got in front, grabbed our helmets off our scooter, and starting walking back to the river with them hehe. Losing those helmets would cost us quite a bit so at this point I decided it wasn't worth it. I coerced the helmets back from him in exchange for a 5,000 Kip note, which he took, ripped into pieces, and threw on the ground before storming off hahaha, dear me. And with that, we carried on and enjoyed more of that scenery.
Now to you and me, $2.50 for example is pittance, but the equivalent of 20,000 Kip is worth considerably more to these people in what is one of the poorest countries in the world. But just because we are "rich westerners" here doesn't mean we deserve to be exploited, which is all this was. Kristina and I have a very tight budget for this trip given we're funding ourselves for seven months through our savings alone, and in order to meet that budget we can't just pander to every unreasonable demand for cash, albeit such small amounts by our standards. Furthermore, the fact this dude tore up my money rather than take it says he doesn't need it - he must make a lot of money out of the unprepared tourists who hand over whatever he demands. The rule of thumb is that if a price is clearly displayed or printed (e.g. bus tickets, restaurant menus, etc) then it is non-negotiable, whereas if no price is displayed (e.g. market stalls, this guy's boat, etc) then it is up for haggling and haggle you definitely should as the price you'll be quoted will always be unreasonable. Fair is fair at the end of day.
