At the beginning of my previous trip I asked a question looking for hawker stalls near Changi airport which attracted an amazing answer about staff canteens that anyone can eat at.
That info came in after I'd already flown out on my connection so I didn't get to try it out, but I'm about to fly the same route in a couple of days.
But I'd like to avoid changing money or using an airport ATM to get Singapore dollars when I'll only be in the country for a few hours.
Can I pay with a Visa card at these canteens, or are the prices too low for them to offer it as a payment option, etc?
