well, lets talk food. You dont need to provide all. IMO. 
though if you were willing to accept donations, I agree. 
But if you would like, I can bring something. (we)
Thats seems equitable for casting. I dont know how many actual readers we have. 
And more than a few of them could be broken up if we wanted to re-cast at the scene break. 
I would also state that if you get drawn for role you just dont want, feel free to say so. 
ie: I will NOT be reading some of those roles in the David Mamet tribute that I right now cannot name. Too many swear words. 
Though really that is a given.
