UA -- are you reading this? Do you see how you've poisoned the brand with your amazing experiment to serve BOB to C class on 3-class domestic service, just to be able to reduce 1 F/A on 16 daily trips that have domestic 3class?

To the OP -- if you are really talking about a 3 class airplane, there is indeed meal service in C now. There was a moronic experiment last autumn, which they backed off of. Having said that, expect a cold meal.
