Sorry, Nicole. If I would have seen your writing, I wouldn't have hired you to begin with.
You will probably start out driving, so be aware of that. When I worked there, only the shift supers, asst managers and managers made pie. It was a really fun job to have.
Make sure you ALWAYS have an extra coke, cheese packs and pepper packs in the car, just in case you get too busy and forget them.
For your interview, just be honest. Customer Service is the main key to success, but being on time for work is just as important.
Wearing? I would wear a nice button down shirt with black pants. At the Dom's that I worked at, you had to buy your own pants and shoes. I wouldn't sweat the small stuff, as it's a pretty laid back atmostphere.
Good luck to you. Be safe on the road. Buy a map.
