Greetings Spanish Speakers!

I recently got hired for a job at McDonalds and I really needed the money, so I plan on staying here for a while. The problem is, I'll be the only crew member who isn't fluent in Spanish, and the manager's English is very hard to understand and more on the Spanglish side. The other crew members all communicate to each other in Spanish as well, and I'm a bit worried I might have a hard time at work.

Is anyone generous enough to offer me some fast-food-related phrases to try and remember for work?
