Didn’t they spend millions on training the crew in fine dining too. Like they sent 55 people or something on a course. Not sure that was necessary.
Anyway, Ratatouille is great but if they did spend a year with rats why have they persisted with the rat trope that rats squeak? They do if they get hurt but at no other time yet when we hear the rats talking from the old lady POV they’re squeaking. Irked.
