Learn English – Noun for person who tells how not to do something, and then does it

meaningnounssingle-word-requests

Okay so I'm sure many people have seen this happen before and it tends to happen apparently intentionally, in more of a way to seem comical, but here is the example for what I am talking about:

"You don't want to over-season the fish at all now…" –covers the
entire bowl with seasoning
– "Alright now we'll season the other side.
Just remember to not season it too much now…" –pretty much uses an
entire bottle of seasoning

So the first word I thought for this would be a "hypocrite", but I don't think it would accurately describe the situation here. To me, a hypocrite is more of this:

"Stop smacking while eating dude that's annoying." –smacks loudly
while eating

Sorry if this doesn't make any sense, but I was just wondering if there was another word (preferably a noun) that more accurately describes the first example.
