Business advisor

I was slowly following Oxford Street towards Oxford Circus. On my left there was some totally smashed fellow, desperately leaning against a lamp post. A few steps from him stood three lost looking girls, clearly not able to make heads or tails of their whereabouts. I stopped and asked if they needed directions. As obviously it was the case I explain to them the way they should follow. They asked me then how much would I charge to take them there. Unfortunately they found my price too dear. I decided that it was no worthy of further haggling and moved on. At that point the boozy looked at me and slurred: "You should change your approach toward customer. You are too desperate!" For a little while I felt completely overwhelmed by his drunken master style. I put myself together though, searched for opponent's weak points and made a quick riposte: "You are too drunk! Sober off and then you will advise me!" I must had found his Achilles heel cause as I was pedalling away, for a long while, I could hear him shouting something about fucking off.
