Often out of stock - Chilli on Top branch

Food *****s run weekly specials however, for 3 consecutive weeks whenever I shop at their Chilli on Top branch they often don't have stock. This week I called the store manager to ask so I can understand why. Half of what is advertised on this week's pamphlet is out of stock. I'm asking them to either stop advertising if they dont have stock on the big boards inside the shop or put up a signage that informs the customers that there's no stock before we waste our time. This is not good customer service. I often go out of my way just to shop at this branch.
