The Souq is a cultural institution of the Middle East.
Everything on show is for sale, only the prices are not listed.
This is because the price varies depending who you are.
Prices for foreigners are twice or more than locals would pay,
and 3rd world foreigners can get a better price than Westerners.
This is based on an 'ability to pay' principle, by which
the more you are able to pay, the more you should pay.
