I did the maths. The overnight bus from Vang Vieng in Laos bound for Bangkok was going to be averaging some kind of record-breakingly slow speed if our arrival time on Khao Sanh Rd was to be believed. Due to park up at 8am on the narrow street that's been the hedonistic centre of Bangkok's backpacker district for decades, at least the sun would be up.
Or not. Because at 5am the bus stopped, the passengers opened their bleary eyes, straightened their shoddy seat-backs and disembarked on orders of the driver.
Apparently we'd arrived. Only this wasn't Khao Sanh Rd.
As packs were heaved on backs and obligatory checks done to make sure no mug-you-while-you-sleep malarkey had happened, it soon became obvious what was going on. We were at a bus depot — possibly an unofficial one — and had a welcome party of taxi drivers to take us to where our bus tickets said was our destination. And predictably enough, they wanted extra money for it.
I heard somebody arguing with the bus driver: "The ticket says Khao Sanh Rd! This is not Khao Sanh Rd!" But it was Bangkok and I vaguely recognised the area, feeling it probably wasn't all that far from where we were meant to be.
