Rule of the thumb is, if not sure, dun U turn, not worthy of the
$150 + 3 points, and if you get into an accident, lagi worst. That
one die die own fault, even chief justice is your father also no
use liao.
So better to go right and make a U turn later, if pax not happy,
apologise and give discount, but if you know that the junction
cannot U turn, tell the pax to go fly kite, if dunno, no choice, hv
to accept and give discount, then later go back to the road again
or google it to check if this junction got U turn or not, like this
you will learn. If pax scold and fark, also good, you learn
faster.
