Your reply doesn't address any of the points of my reply. Once more: Why would it be relevant at all that something works for restaurants, a completely different environment? Mentioning restaurants does not work to refute the article's points.

Yes the article is horrible. It's not even an article. But that does not mean you can now go ahead and use anything to refute it. That's illogical. You have to use good logic even when trying to refute something bad.
