First day of work sucked!

Just a rant about my first day of work delivering pizzas. So, when I was being trained basically, the person that I was with made me do the last two deliveries while I was with him. And it was basically impossible to find the last house. There were about 5 mailboxes in a row that weren't designated to any specific house, so we had to go up to all of the houses and look at them. And when we got up there, the houses weren't even numbered! So we just had to guess and we knocked on 2 doors before we got the correct one. Then, on my first delivery on my own, my GPS got me lost and it told me to turn down somewhere which I thought was just a narrow road. It turned out to be someone's driveway... and then it was extremely hard to back out of it without running into the ditch/trees on either side of me. So that was really crappy. My second delivery went okay, it was an apartment and I'm not used to going to those so it took me a bit to find the correct one but I found it and everything was okay! Both of the people that I delivered to also tipped me $5 so that was great! But then at the end of the day when I was counting my money, I realized that I was missing $30... so I had to tell my manager and I was written up on my first day. I called back both of the houses that I delivered to and one of them ended up finding it, thank God, so I'm going to go back and get that. I just feel really really bad about everything. Hopefully today is better
