Yes, that's what stood out to me. He "assumed" nobody else wanted it, instead of asking--can't point out that there's sandwich left, because someone might gasp take some away from him! Any decent person ASKS, loudly and repeatedly, if anyone wants any more before finishing off the entire last half of a goddamn party sub. Most decent people would ask the hostess specifically after asking the other guests. Everyone--sorry, every normal person--knows not to just take the last of whatever group food is available without asking. It's why offices always have one single cookie or donut left a week after the rest of the food was demolished.
