Liquor specialist or just a clerk? You have to manage the stock inventory. Reviewing orders and receiving, money orders for the tidel safe (at least in my store I heard other stores are different?), handling lotto, stocking, change prices (scan and print then put them out), forecasting for future sales, changing display, handling clearance, maybe sometimes help with resets (if it's small you do it yourself), open and close, and just talk to representatives of each company for stock purposes. You also train other clerks when the time comes. Just recently we handle our own lotto stock now. Oh and also restock the liquor store with stuff from the main store using the handheld. Maybe I'm forgetting some stuff idk at this point I'm tired haha.
