Just wanting to know a good trustworthy money Exchange in Patong ?
Just go for the one offering the best rate
Make sure you count your money & put it away safely, before you walk away from the booth
But don’t spend all day looking for the ‘best rate’ You could well spend 2 or 3 hours trying to save $3 or $4 and I doubt you’d do that when buying something back home.
Posts 1 and 2 contain good advice. I once buggarised around for almost 2 hours walking from exchange booth to booth trying to get the best deal. Exchanged 500 AUD and saved myself around $4-5 compared to the 1st booth I checked. It was, on reflection, a ridiculous waste of time and a silly way to spend 2 hours on holiday. Nowadays I check between 3-5 booths (maximum) and go with best rate and get back to my holiday. Good luck.
My advice is this.
Patong has so many. Google the rate and walk around and try to get as close to that as possible. As indicated above you probably shouldn't waste too much time but DO in fact check around. You will find some are rip offs and I actually got 100 BAHT more by checking around. Just don't overthink :)
