Simple mistakes 10. Not mentioning your apartment number. If you live in an apartment, please give the order taker your apartment number when you order pizza. This is an essential part of your address. Most drivers don't know it's an apartment before they leave. They get closer to the address and then discover it's an apartment complex. There are too many apartments to check and someone else would likely claim your pizza. The driver must return to the store and call the customer. It will more than triple your drive time.
