Next to the shop is a sign announcing that the knights and paladins are keeping a watchful eye on things; mainly by noting how many items are being stolen from the bakers' stalls. Therefore, being caught stealing from this particular stall may result in one of the higher levelled guards, a knight or paladin, attacking you. Lower levelled players should take caution when doing so when food is not on hand. You can run away from the area around 15 squares away and then return, the guards will not attack you now but will if you get caught again.
