Absolutely. I had an order tonight, that tipped $5. When I got back to the store, the phone was ringing, I answered, and it was my customer, they had gotten the wrong kind of wings. I got the manager on the phone, and told her that the person was a good tipper.
We do get occasional scammers trying to get free food, but they don't tip. This customer got their remake of wings in about 15 minutes, and I didn't collect the wrong order either.
Totals for the 5 hour shift were 8 deliveries (7 plus the rerun), 42 miles, and $23 in tips.
