Amanda Bynes does not hold back when it comes to the weed ... or the munchies.
We don't know that for sure, because we weren't there, but we do know she racked up a MASSIVE room service bill before getting booted out of her hotel Thursday.
The one-woman Twitter tornado spent over TWO GRAND there in a week-plus.
She was kicked out of the Ritz-Carlton for smoking weed in her room, as well as for being repeatedly rude to the staff (who she called "ugly" obviously).
Amanda Bynes denies the allegations ... but the bill does not help her cause.
