I forgot this: Jax Does Bartering

I kept on seeing Bintang everywhere.  It's apparently Indonesia's favourite beer.  I have now had one.  (At Jackie's place.  He doesn't own it, I don't think, but in my mind it's his place.)  And I'd seen some nice t-shirts and vest-tops with it on them.  I thought 'this would be a nice souvenir of the holiday, as long as I also drink one: it's quite nice, fairly standard and inoffensive beer.  I.e. along the Sol/Corona/um...green bottle, English? type beer.  Rather than that really strong tasting stuff that you get from Real Ale places like The Fat Cat (in Norwich). 

So, in a shop with all this 'cut price' stuff, the type you see everywhere, I found a top I liked.  I looked at it, critically.  (Don't show too much interest.)

One man said to me "100" - which means 100,000 IDR".

I had read in The Book, that you usually offered, first, a third or half of the price, and then they counter-offered, and eventually you agreed on about 2/3 of the price.
I said, "300" (which means 300,000 IDR).  The man looked confused.
I said, "I mean 600."
Zoe managed to get me to then say '60' instead.
Another man in the shop came up.
He said, "120."
I said, "Wait, that man said 100."
Then I said to Zoe, "Hmm, do you think it'll be a bit see-through."  (Cunning move!)
I said, "60."
He said, "You have to give me over 100."
I said, "70."
Zoe said, "Come on, let's go."
He said, "Ok, 70."
I said, "80."
He said, "Ok."
I said, "Wait, I meant 70...."  But it was too late.  D'oh.
Still, that was my first bit of bartering.
Good thing Zoe was there.
