I’m sorry I did not see this post before I travelled to Egypt, almost fell for the “baker from your hotel” scam at Luxor, but did not follow the guy to the market to buy anything. Eventually, he just asked for a dollar, gave it to him to leave me alone.
Other things to be aware of:
-dyed black pepper sold as red/green peppercorn (yep, bought some)
-agreeing on a price and then getting asked/begged/threatened for more because it’s different size/further away/better quality (encountered all of these)
-having paid your hotel bill and being told “that this bill just came from the restaurant with your room number on it”. Make sure you sign receipts in a distinctive way or just write your full name.
