For my first 3-4 deliveries tonight there was a light rain falling. At my 2nd house, I knocked, and a man opened the door (not the storm door) and growled back into the house "somebody order pizza?"
I stood there (in the rain) for 2 or 3 minutes before a woman finally came and signed (it was a credit card order) for the pizza. Of course the credit slip was pretty wet. They seemed oblivious to me standing out in it.
Totals for the night were 5 hours, just 7 deliveries, 32 miles, and $18 in tips.
