Kuta Is not seminyak Christian ( although parts might be getting more like it I grant you day by day) and I would disagree with you Seminyak looking like Phuket etc, perhaps small parts, but once you travel out and about there are some beautiful buildings, bars and restaurants and ocean views abounding in the local area. I'm also guessing that you also didn't interact well with the locals or feel the relaxed and chilled out vibe in the area ( as I'm guessing you've never felt chilled out and relaxed in your life and a staff member from one of the bars you were in was able to tell me you'd been rude to them - in their opinion and had asked for some info, got your answer, they then tried to interact with you further and you cut them dead and ignored them), the chilled out and being friendly thing Is all part of life here it seems and makes a trip enjoyable - the same as anywhere else I'm guessing and is also the reason you probably don't enjoy too many other places that most seem to find ok too.
And to be monetary for just a second ( which I know you'll like) one MASSIVE difference is that it seems that one can shag themselves to a standstill here, perhaps two and three times a day, every day and over for a reasonably long holiday period at that - and for FREE - try doing THAT in Thailand for even a week ! Hell you live there and still can't seem to manage it in any organised or regular way with having to do a mountain of work to achieve that, here, it's an App reply and a meet 15 minutes later - so I'm told anyway if my BF reads this later !
And re the money changer yes of course I'm familiar with the money must be counted before leaving the store rules etc - but when I went back it wasn't a contract I was waving at him but more my fist and a "real world" proposition of "there's two ways we can sort this out, up to you how"' - and as I said I was both very relieved and surprised that he picked my way - but remember he stole 2.7 million and I only got back 2,2 - so he was still 500 up ! For stealing and me not breaking his face or calling the police, so on reflection he made the right choice. And yes I did of course count my money but he simply pinched some of it back when I averted my gaze for a mere millisecond.
