- Increases normal snack machine prices
- Adds Discount Dan's vending machine
- Adds Discount Dan's Special Sauce 
- Adds Groans Soda
- Adds many junkfoods

Discount Dan's special sauce is almost harmless besides being annoying. 

Hopefully this will increase dependency on the chef, now that he can handle a greater influx of demands.
