Did you know that if you don't tip a pizza delivery person, they write down your address in a book.....?

Well, there may be someplaces where that information is posted on a blog, accessable to all food delivery places, and all food delivery people take actions such as you describe and/or deliver late (last). So if your food gets delivered later than you think it should be that might be what has happened. Also, usually change is not given for foodstamps in the case of welfare mother.
