My company kicked back an expense report for a breakfast at Applebee's for being extravagant...
I really honestly don't understand how accountants who don't travel for business think that you're going to be able to survive on $30/day, two to three meals per day for weeks.
I mean if you're eating like a kindergartener with chips, donuts and McDonalds cheeseburgers, sure. But if you're an adult that hopefully plans on living a long, healthy life, nutritious food (and a decent beer or two) costs loot.
