I would not consider filling 10 gas cans as hoarding. Gas doesn't last long if you have a truck to feed, a generator, a cookstove, and even an unprepared neighbor or two. Imagine the trade value of a filled 5 gallon gas can in a post Katrina scenario. I believe rather than using a lame excuse, the correct reply should have been. "I need it, I'm paying for it, why do you care?" MYOB
