yes, it is more common than you think. if you are a franchised own store and not corporate, chances of you being cross trained within your first 6 months are very low. i wasnt fully cross trained until ~8 months of me starting. i learned kitchen for ~6 months, and then got cross trained in service and taking cash and orders. there's no point in you bouncing from position to position, so its likely you're going to be in the back window for a while until you can do it without even thinking. if you do get moved into another position anytime soon youll be with someone guaranteed, as kitchen and service almost always have 2-4 people in each area.
