A Stall is a stand that NPCs use to display their product, the majority of stalls can be stolen from with appropriate level in Thieving. Items sold include, Silk, Fur, Scimitars, Fish, Vegetables, etc. Most types of stalls can be found in Ardougne however there is also a selection in Rellekka, Miscellania, Sophanem and Draynor. Stealing from a stall may alert a nearby guard who will attack until they die or the area is left. Stall owners will not talk to players if they have stolen from their stall within the last 20 minutes unless you have a vial of stench (a). It's not needed for the stalls found on Ape Atoll.
Note: In Keldagrim, stalls often differ in respawn time and their experience given. The silver stalls respawn twice as fast, but yield half the experience. The bakery stall, however, respawns twice as slow, but gives twice the experience.
