Rene looks intensely skeptical, in a way only someone with as many pilfered snacks as he has had can manage.

Generally speaking, he takes too-snooty-for-free-luxuries as someone-never-had-to-go-without-them, but for once in his life he doesn't throw that assumption out as a barb. He is, in fact, much too sat down and relaxed to be acting like too much of a dick right now. That takes energy and focus! "Your loss," he shrugs, instead of even considering that she's got a point.
