mike gets scammed

After church today I stopped at the Subway (I'm batching) for a sandwich to take home. The cost was $7.09 and I gave the guy a 10. I say, "I think I have the $.09." He holds up a dime and says, "I got you covered." and hands me my sandwich. I am about a block from home and think, "He did not give me the three dollars change1" and then think, "How did he come with that dime so easy?"

He got me this time.
