Crazy taxis

The reason why I cannot wait to get a car is because I am sick of getting cabs around. There are no street addresses here, so each call-cab affair involves me getting on the phone directing a cabbie on how to get to me. Most of them are pretty ok but occasionally you get the really dumb ones that have absolutely no clue, and refuse to listen to what you're saying.

A sample conversation was my colleague and I getting a cab to get us from the office today. Cab asks where we are, we tell him, he says 10 minutes. 15 minutes later, still no cab, so we call him. This is the conversation on my colleague's side:

"Where are you?"
"Can you speak English or Hindi? I cannot speak Arabic or Pashtun.."
"OK you are at 2454?"
"OK, which roundabout??" (there are like 5 around my office)
"No, what do you see, tell me what you see"
"Do you see the pink concrete wall that borders the airbase?" Go towards that, take a right and you will see the building on the right"
"NO NO NO, we are not at 2454. We are at xxxx "
"Listen to me, we are not at 2454, we are at xxxx, You know xxxx?" (obviously he has no clue!)
"Ok we will wait at the road"
Colleague puts down the phone and we both heave a big sigh...

10 mins later, still no cab. Colleague gets on the phone and calls cabbie..

"Where are you?"
"What??! We are not at Cafe Colombia, I know where that is. You have to come to xxxx"
"OK, who is this?" (Cabbie had passed the phone to someone else!)
"Do you see the pink wall, go straight towards it and turn left, ....."

The conversation goes on for another 5 minutes and colleague puts down the phone cursing..

We wait and see a cab passing on the opposite side, so we wave at him, and expect him to make a u-turn..but 3 mins later, no cab! We got so pissed off that I called another cab, and a total of 30 mins later we were finally in a cab.

This wasn't an isolated incident, and I've had so many conversations like that ("Yes i know you are at a roundabout but there are 5 around the office, what do you see, tell me what you see!). It's really annoying and tiring to deal with this so i cannot cannot wait for the car!
