look at another perspective, she might be angry with u because u didn't ask permission from her first. imagine you in her postion. you arrange all the stock and box nicely, put it up so that no body will tremble over it. then suddenly come one guy start taking down the box korek2 mess up the thing that you have just arrange, sure you'll not be happy right? for me if i see box above, i'll try to find the person in charge. if i see the box on the floor and got staff around, i'll ask their permission too. but if really cannot find anybody around, then u pandai2 la. :p
