>. I don't have to tip / it's not required.
Of course, tipping is not mandatory. We're not disputing that. You can choose not to tip if you want.
However, this objection is a moot point.
It doesn't make it right. Just because you can do something, it doesn't mean it's right.
You can steal the services of the driver if you want, but it's morally wrong. You can be a cheap jerk if you want, but it's not okay. You can insult the driver with a lame 17-cent tip if you choose, but it's a cruel thing to do.
The driver still had to deliver your pizza, wear down his or her own car, endure bad weather, risk damage to life and property, and waste precious time doing it.
This is no excuse. We're sorry, but you can't use any excuse to justify rude behavior.
Please order pick-up (carry-out) if you're not going to tip. Don't make the driver waste valuable time on a worthless delivery.
Why order if you're not going to tip? If the service is not worth tipping, it must not be worth having
