Be on fitting room, clearing fitting room rail/delivery rail, processing delivery which entails unpacking clothes and hanging it and then security tagging it. Being on "front" basically standing at the front of the shop and greeting customers whilst having the store net radio if the shop uses store net and you're store net trained. Um....general cleaning, hoovering etc, polishing mirrors. Sorting stock room. Changing displays. Cleaning canteen/staff room as in doing the dishes etc....
The list goes on and on and depends where you work really. I work in Republic. There's always something to do. Boring though after a while. But fun too if you get on with the people there as I do!
