I know you are, but what am I?

Pizza delivery brings a whole new level to the childhood game "I know you are, but what am I?" although in our case, I call it "I know you know you live there but how am I supposed to know you live there?"

For example, in Australia (I'm not sure about other countries) and especially in my delivery area there are a lot of apartment buildings. Addresses run as apartment number first and building number second. For example, 19/57-59 means until 19 in the building that spans blocks 57 and 59 of the particular street. Not hard, right?

Well, you have your normal reversals. So, 2/16 becomes 16/2 and you end up bothering some poor old lady at 2am. You've got your wrong apartments- 14/2 becomes 15/2 and you spend 10 minutes banging on the wrong door before the customer comes out to find what all the noise is. You've got people that live at 2A that tell you 2 (see above result) and then there's the people that live at 2 hill road but tell you 2 hall road and you end up in the wrong suburb. Sometimes they're not even home when you arrive! They order on the way home but get stuck in traffic. Or they are home but asleep in the bathtub.

Better yet are the addresses that are incorrect with an incorrect phone number also. This means not only do you not know where they live but you can't even call them to confirm it. Fortunately if it's a regular you can usually figure out the correct address and deliver it anyway, but sometimes it's just not possible.

Worse still are the games of "I know you know you live there, but how am I supposed to know you live there?" that are played late at night on a dark street full of houses and NOT ONE SINGLE ONE HAS A HOUSE NUMBER! Please, make sure that your house has a clearly visible number somewhere on the letterbox or fence of possible. This means don't put white numbers on a white mail box, or bronze numbers on a brown fence. It just makes it that much harder to find you and get your pizzas to you. We know you're hungry and we're doing our best.

What makes it all worthwhile? Seeing the happy little smiling faces and hearing the little voices yell "MUMMY! PIZZA'S HERE!!!" and knowing it's a job well done.
