For 2pm I would probably also be surprised, but pleasantly so, about a large amount of food being available. It's somewhat of an ambiguous time, being the end of the lunch block, so she could've gotten away with something much lighter, but it was nice of her to serve more. I might be disappointed that I didn't have room for all the goodies she was serving, but that doesn't really indicate an error on her part, you know what I mean? Since the main event wasn't eating, and she was serving more than one might expect, I don't think the hostess had an obligation to make the food choices clear to anyone in advance.
