Buying meat in the Middle East is just as easy as buying anything else. You go down to the market, find the relevant section and shop around for the best price... and of course haggle and negotiate until you're happy with the price.
The good thing is that all the meat is hanging before your eyes ready for inspection. The bad thing is... well, let's just say food safety laws don't really exist in the Middle East. But don't worry, this is how things are done here and the chance of dying from contaminated-meat poisoning is only moderate.
But look on the positive side... all the meat is smoked at no extra charge - smoked from exhaust fumes of cars driving immediately past.
