Benjy liked the surprise of not asking for specific things. It put the Elves to work, sure, but he always ended up pleasantly surprised. But he was also a pureblood and really didn't see the issues with putting the House Elves to work. And the surprise was fun!
Taking the two whole trays of sandwiches that were brought over to them, far too many for just two and a half people, Benjy thanked the elves and took what few things he could that they tried to push on him as they walked out of the kitchens. Going in there was fun but always a little overwhelming.
