That, along with the rest of what you described is far too many red lights for me, Jun, especially the boys glued to their phones like that. If it were me, I would have left in that same Grab taxi and either gone elsewhere or perhaps back to my room and gotten a boy from the apps or, if necessary, a 'self-service' massage that day . . .
I hope the massage you did get turned out to be worth the wait.
One question that has been puzzling me for a long time. So many people from so many walks of life in so many different locales are all glued to their phones. What the hell are they all looking at that is so fascinating?
