Ouch.

I know what you mean by that. I once worked in a place where everybody was responsible for everything. That was fine when it was a slow to average sort of day. During the rush (there were at least 3 separate and unique "rushes") it was pure chaos. You couldn't keep stuff straight, customers got cranky (Customer service was #1 priority, even if it meant that you couldn't get away from the counter to make the food for the customers to buy).
