Until I opened a Thai bank account, I used to change sterling at one of the many FX kiosks. Not once did anyone attempt to short-change me.
In 2018, I spent 3 months mainly in Sanur, on the south-east coast of Bali. Almost every time I exchanged currency, there was an attempt to short-change me. One of the tricks they employed was to try and pay me in low-denomination notes, making it more difficult to check the amount. On another occasion, with the FX rate clearly displayed, and a notice claiming "No commission" the man tried hid darndest to fiddle me. I had put 2 £50 notes under a rock on his counter. He was putting bundles of IDR on the counter but, as I was counting them, in my peripheral vision I noticed he was removing some which I had already counted. When I challenged him, he said, "I have to make a little commission!" I swiftly retrieved my 2 £50 notes and walked away.
On the subject of food, I thought that the fare may have been even more diverse than here in Thailand --- what a misconception that turned out to be? A lot of the meals seemed to be topped off with the same boring sauce/gravy. Also, because there is a hefty import tax, or so I was told, the Aussie steaks were more expensive than some here in Thailand.
