I am the one who always finds that queue
5 minutes is reality. A couple doing misc attempts on her phone, then doing misc attempts on his phone. Finally giving up and organizing the enormous amount of 4xx Baht in cash.
Which ends with the cashier calling the supervisor to clean up the mess.
Smaller events again and again. Cashier is ready, amount on display. What now?
Where is my phone? Digging, where is the banking app? Swipe swipe swipe...
(and I silently repeat the mantra: never loose temper/face in Thailand, keep calm).
I use cashless where it's appropriate. Paid 2xxk hospital, paid 6xxk final payment for new car. Pay utilities online, no cash on delivery at Lazada et.al. But not my snacks at 7/11!
