Money changers are soon going to be obsolete... it's so much easier and cost effective to use YouTrip, Revolut, Wise when you travel. I can't even remember when was the last time I step into those ah nehs money changer shop to buy foreign currency... of course I hope the old school money changers will still be around for they are needed to keep the currency exchange rates on YouTrip, Revolut, Wise favourable for people like me.
