Eh. This is the sort of thing I would (and might) recommend to my restaurant-owning clients free-of-charge, which is why they call me when they have other trouble, and why they recommend me to other people, which is where I make money.
That's not to say that it's a bad idea, just that it wouldn't change my recommendations, personally.
