That's not what the example "shows". The standards aren't raised, but lowered. First, let's just agree on some terminology health codes are the "standard". If you only clean before an inspector arrives (and you are sure that that's the only time to do so) your standard is lower on average over periods of time or altogether, depending on the offense. If you don't know when the inspector is going to arrive, you are incentivized to keep to the code at all times, which is the reason you aren't supposed to know.
