never walk in front of anyone who is praying in the street, they loose their contact with Mecca & have to start again, its very disrepectful.
Dont sit with your feet up, so they can see the soles of your feet/shoes, also disrespectful.
Price of gold is set in the gold market each day, all shops use this pricing, you choose your item i.e.bracelet earrings and they weigh it, then calculate the price, so if you go next day the price could be more or even less depending on the price fixed that day. They will take old gold in p/x for something nes but not, I'm afraid 9ct as they consider that impure[ quite true] sh*t gold they call it and wont touch it, makes you laugh when you come back to UK and womeb are proudly wearing tons of it round their necks !.
Try using the abbra [ water taxi] to cross the Dubai Creek, its fun and cheap or you can have one to yourself for a little more. My old dad at 78 yrs young used to love the abbra , he would go with the flow and the locals used to help him on and off.Cover up when out shopping, or expect to be oogled as their femaled are coverd up.
I will continue on a seperate posting as I tried to post altogether and Answerbank said too many words.
