I've not ever noticed it before in quite this way; where they didn't take a polite "no" for an answer but just kept coming. It was a little shocking, really. And the pitches are all for liquor and/or dining packages. There must be HUGE margin in those. They've even got the regular waiters trying to sell dining packages in the MDR but suggesting how much better the food in the specialty venues is than what you're about to be served...
