I found that having to pay for trolleys new too. Like if I was new and didnt have the currency of that country n really needed a trolley, i would have been forced to use my credit card just fr 2 dollars.
I'm used to the airport in Narita, Japan and the trolleys are free, big and have those handle locks. But oh well, cant be helped
U may not necessarily use your Cr Card... the ICE Kiosk could exchange your Forex [albeit at reduced rates though].
But, yes that $2
thing is a hassle anyday. However, being gradually implemented in all a/ports around the world. Blame it on recession...Qorax
