How to close a sale

While walking down the main shopping district, a street seller caught my eye as he was selling these really cool templates for drawing geometric patters. (I have a lifelong fascination with geometric patterns, which incidentally makes the Islamic mosaic art very attractive.)

Anyway, he saw my glance and was so committed to getting the sale that he picked up his stall and chased us down the road!  Negotiating all the way. This guy was serious. We were crossing the road and he put his stall down in the middle fo the road (!!) to stop us.  Cars were driving around us on both sides while I negotiated the price down from 35 Turkish Lira.

By this stage, I was so impressed by his tenacity I couldn't say no. We settled on 5TL and I got my geometric templates.
 
Now THAT GUY knows how to close a sale.  No wonder I was always crap at sales - I'm just not that committed.
