You can use my advice or pitch it.
I'm a customer of pizza hut delivery. Why? The delivery driver comes to my door excited, ambitious, and complimentary. He earns a 30% tip everytime!
How does he do this?
When he arrives at my door, he's smiling and thanking me, by name, for the order. After he's paid, he thanks me for his tip, then tells me with a smile, "enjoy your pizza and your evening."
Guess what? When I order Pizza Hut, he's the only driver allowed to deliver my pizza.
Approach this job as if it is your career. People will take notice, and your monetary rewards will exceed your expectations. And, the manager will start to question why people are requesting you as their delivery person.
You're not delivering pizza! You're delivering a meal, fun, relaxation, convenience, etc.
Practice these steps and come back to report to us how well you do.
