You push your way politely to near the front of the queue and wait.
And wait.
And wait.
After 15 minutes, not one taxi has arrived.
You can:
Give up and
walk
to your hotel.
Wait
patiently. There's bound to be a taxi sooner or later...
Head for a main road and try to
hail
a taxi on its way to the rank.
Throw caution to the wind and
take the tube.
Brr! It's cold standing here.
