If they can strike, more power to them. Maybe it will weed out the fast food restaurants that aren't popular due to crummy food. In-n-Out pays well above minimum wage to start, and they do quite well, because they offer a superior product.
Maybe you shouldn't be bitching about what other workers seek in the world, but instead about the idea that any business should succeed, even if they produce a lousy product.
And don't pull the line about how it's going to make lunch prices go up. In-n-Out offers a soda, a delicious cheeseburger and delicious fries (all from fresh ingredients trucked to the store daily) for about $5.00.
It's not the workers' fault here. It's businesses which choose not to streamline their process and offer a superior product and service that are at fault.
Essentially, it sounds like you're advocating a sloppy and lazy business plan. Quit your whining, enjoy your job, and instead of complaining about workers seek in this world, why don't you go enjoy a nice lunch somewhere?
