Very simple:
Small device like a calculator, actually it would be a
caclulator... with an infrared sensor. Put it on top of the pizza
box when it arrives, type in the cost of the bill, sensor
measures the tempurature of the pizza and calulates tip
accordingly. Notion: would encourage delivery
guys to be
timely; which of course could lead to speeding...
Would work for other foods too.

How about one of those cheap liquid crystal themometers (the ones you use for childrens temps) actually stuck to the box top. Instead of temperature it could be calibrated with suggested tip. |

I was expecting this to tell me whether a tip was a hot tip or just a tip. |

We've done the 'built-in thermometer' idea. Not for tipping, though. |
