On the minimum wage subject, when I started delivering for Papa John's back in 2006, we got paid what minimum wage was, $5.15, and when they raised it to $5.85 a year or so later in 2007, they paid us that. But they refused to go any higher because this was during that time when the US government raised minimum wage 3 times in 3 years, since they obviously neglected it and had not raised it since 1997.
The company I deliver for now does it in a strange way.... $7.25 in the store, $4.25 when on deliveries. Of course, the tips make up 2/3 of my pay

Getting back to the main subject, this man was just irritable, mean, and cheap. It seemed very much like he was irritated with me because of his stupid dogs barking. Some might say, "Maybe he didn't have enough to tip?" Bullshit. The way I see it, if they can spend $15 on food, they sure as hell can throw in a couple extra bucks. Heck, I am just barely below the poverty level and guess what? I tip drivers and waiters. However, I should also point out that if the service is terrible at a restaraunt, I will leave little to no tip. A couple times in the past when my pizza took forever to get to my house and they comped my order, I would tip the delivery driver at least $3.
