RE: [business-transaction] FW: Infinite Loops and webservices

[Peter Furniss <peter.furniss@choreology.com>]

ancient tale, in the butcher's shop:

Shopper: "how much are your sausages ?"

Butcher: "Four denarii a pound"  [i said it was ancient]

Shopper: "But in the shop over the road the price is three denarii"

Butcher :"Why don't you buy them there then ?"

Shopper: "He hasn't got any left"

Butcher: "Ah. When I haven't got any sausages, my price is only two denarii"
