When we were in college, many years ago, our phone number was one off from a pizza delivery place. We'd get calls all night long from drunk kids, so we just got to where we took their order and told them we'd be there in 45 minutes. Most of the calls came in after the pizza place had closed. I did call the pizza place after the first call to tell them what I'd done, and the owner just laughed and said it wasn't hurting his business any and keep it up. They hated delivering to drunks anyway...bad tippers and usually rude to the delivery guys. After a few months, we gave up and had our number changed.
