July 4, 2014: This morning, around 10:30 am, me and my wife were taking SARL from Makkasan Station to airport. The ticket officer asked for B70 (B35 each person) and issued 2 tokens. The tokens failed to activate the turnstile for us to exit when we arrived at the airport. We had to top-up another B30 (B15 each) to exit. A lady behind us paid B10 to top-up her token. I think she was local as she grumbled something like it happens often.
How, as a tourist rushing to go home, to avoid the cheat in future. Going to police or returning to Makkasan is out of the question.
