Is It OK for Guests to Load Up Leftovers When They Leave?

Are you still munching on Thanksgiving leftovers? Better eat 'em up fast, because before you know it, Christmas dinner will be here and you'll be feasting on tons of leftover food all over again.

Having leftovers is one thing, but offering leftovers to guests is another. Rik says at his Thanksgiving there's a person who always brings their own Tupperware containers and loads up on leftovers without asking the host. Seriously!?

Have you ever heard of anyone bringing their own containers for leftovers and loading up?
