Wait for cab.

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.
