Free food

Schneier has an interesting bit about how people steal free food from a drivethru. So let's assume you had a Mac-attack, is this really the best you can do? Do you think you could apply this to say a drive-thru Starbucks or cleaners (not that Leon's suits would come close to fitting me)? I mean if you have money enough to own a car and put gas into it, why would you need to do this? There's a reason they call it a Value Menu!
