The ultimater sales trick!

Wanted to buy a tumble dryer. Mr Rafi himself(!) with calculator in hand inquired about the price quoted (R7500). Punching the calculator, he came up with a special price of R6850. Proceeding to payment, the price jumped to R7644 (!). On objecting to the sudden jump in price, the old adage ~ You dunno wanta mee to mayka profeet?` I could not trust this fellow. So, no deal and left the shop in disgust. NO business from me ever.
