Think about it! They're working all the time and are seldom at home, and the money that they earn can't buy more than what they actually need, sometimes even less than that. In fact, these delivery guys would definitely appreciate it if you gave them something else other than money. So why not step up your tipping game and give the next pizza delivery guy more than what you usually tip them, right? Your tip doesn't really need to be in the form of cash or loose change. It's a mystery why there are still those who choose to deliver pizzas for a living when the circumstances are like that. Sadly, this is how most pizza delivery guys live their life.
