Room service in Karachi

Amit varma from IndiaUncut has this funny conversation on his blog. 

Overheard in my hotel room at Karachi: My room-mate: Hello, room service? Disembodied voice: Yes. Room-mate: I'm calling from room 225, can you help me with potty, please? Voice: Certainly sir. For one person or two persons? Half-an-hour later, pot tea came.
