I have a question for the peeps that set up their shops in the section outside the warehouse in the hallway, dont you peeps know that if anyone wants to buy that stuff they will come and look for it? Half the freaking courtyard is empty, use it, you peeps blocking that hallway and those archways is annoying as heck, I hate it when i have to look for that little spot to get through the archway to go to the grocery coming from the warehouse.
I always look for a unpopulated spot to sit down, and then stay there on a semi permanent basis. Giran however, is somewhat difficult as it's fairly easy to get lost in the crowd.
My suggestion is if folks are always selling the same thing... Pick a spot and stick to it. Then people who tend to shop for the things you happen to sell will always know where abouts you are.
But .. do try to stay out of the way of traffic, nothing is more frustrating then trying to pick your way thru a area that's heavily populated with shops.
