There are four separate screens to deal with your food stocks - purchasing, pricing, inventories - and none are linked, so you have to flick back and forth endlessly. Even working out whether the floor is dirty requires you to desperately scan the room. Aside from that, the main problems you face are where the game omits to automate a process, e.g., you need to manually order floors to be cleaned until you upgrade to a level 4 shop - at which point, the shop just keeps on ticking as long as you order stocks. In other words, for a strategy game, there's laughably little strategy. It even resorts to sub-Flash games - rat whacking, UFO zapping - in an attempt to distract from the tedium.
Oh - and it's clearly sexist too. But that's the least of its problems.
