You made that assumption so explicitly that there is already another comment objecting to it:

> There's nothing about a 1-10 scale that implies that every visit to the restaurant will be equally pleasurable.

They just made the same incorrect inference that you did, that's all, but they did so more politely. In my response, which I linked for you earlier in this thread, I pointed out one way my original comment took those complexities into account in what you evidently think is my Grand Unified Theory of Restaurant Hedonics.
