[Sundae]

Now you should have said that in the first place!
A black waitress who is slightly larger than the average supermodel is a great cast member for a zombie movie.

I will have to rewrite part of it just to include you.
You'll need to work in a diner of course. Silver service doesn't cut it for this film. With a walk in freezer.
Am in two minds as to whether you get locked in or whether you lock someone else in.
Oh! Could you have an addicted younger brother (or friend - can cross racial lines when it comes to skinny people)? Yes - he's one of the early zombies who you lock in to protect all your ungrateful customers who think you are bringing your problems to work and they just want coffee, damnit! Then some do-gooder lets him out because it's just withdrawal, not zombieism. Uh-oh, who's sorry now...?

You can survive that scene because I think you need to slap the fat-arse drunk female later, to try to get across how you know all about addiction and you couldn't save your brother/ friend but you can save her. You don't of course.
