Delivery Driving

Last night we get a delivery order around 10pm. I decide I'm willing to take one more because I haven't quite counted out yet. He told me it was 433 n and it was a basement apartment. He instructed me to go in the back door, go down the stairs, and knock on the door. When I arrived at the location I thought that all the odd numbers were on the left. I saw a 440 and there was a complex next to it. I assumed the basement apartment had a different number and proceeded to let myself in the back door and walked down the stairs. There was no door, just a hallway with bedrooms. I realized I was probably in the wrong place. I heard talking in the kitchen and wasn't sure if they had heard me come in, so I went up to explain myself. They were having a "Clue" party and thus were all dressed in ridiculous costumes pertaining to the characters. They weren't mad, but asked me to take some pictures of the group of them in costume. They then proceeded to tip me a dollar. I left, went across the street, and delivered the pizza. He tipped $8 and laughed at my mistake.
