I've flown this every 2 or 3 months for the last 1.5 years and been upgraded a couple of times. I usually get drink service in F (they took drink orders for the air during pre-departure beverage) but in Y it's either water service or nothing.

That being said, I have received meal service on flights this short before, just not on CO/UA ^

Also, I wouldn't eat the F meal as I would want some Salt Lick BBQ and Amy's Ice Cream before I left.
