Run home to get something to eat, then if you HAVE to come back, you can bring the mando with you! ;o)
I'm ALMOST tempted to do that. I would have to come back. Thing is, I don't have time to run there and back in my lunch hour (though I've done it), and I don't like playing music when other people are in the office...usually what happens is everyone else goes somewhere else to eat lunch (like the dining hall, which is...closed), and I play while they're out.
I think I can stand to wait until evening. But I miss it! ;-)
