I'm curious: is the "please" you added purely a communication habit or does it lead the model to provide better results?

It is perhaps unnecessary, and I don't have any data that would support that it makes things better, but I am basically guessing that in the training set of {mostly the entire internet} the responses to questions that include "please" might be ever so slightly higher quality! Perhaps it is just a superstition...
