Tube Trouble

I jumped on the Victoria line tube at Euston yesterday, having just arrived in London from Manchester. Next to me was a youngish guy of Pakistani origin (to be politically correct). The following conversation ensued:

Pak: Is this the tube for Oxford Circus?
Me: Yes
Pak: [something unintelligible in Urdu]
Me: I can't hear you
Pak: [something unintelligible in Urdu]
Me: I don't understand
Pak: Don't you speak Urdu?
Me: No
Pak: What do you speak then?
Me: Bengali
Pak: Oh right, you must live in East London then
Me: No
Pak: Don't you like East London? I thought all Bengalis lived there?
Me: (rolls eyes)
Pak: What's your name?
Me: I don't think you need to know that.
Pak: I'm not flirting with you [laughs lightly]
Me: Good, because I'm married (lifts left hand to show ring)
Pak: What's the point of letting me flirt with you all this time then? Anyway, for friendship it doesn't matter if you're married or unmarried..

Thankfully, his tube stop then arrived. I think next time I should pretend I don't speak any English, or maybe poking them in the eye would be the more expedient way of getting rid of these people.
