Coworker: Where cake?
Me: What do you mean?  I bring in baked goods on Monday.
Coworker: No, you bring on Tuesday sometime, even Wednesday.
Me: I’ve never brought in a baked good on a day besides the first in a work week.
Coworker: You bring in cake on Friday last week.
Me: I wasn’t even in on Friday last week.
Coworker: You always bring in cake each day.  I remember.
Me: Sam, have I ever brought in a cake on Wednesday?
Sam: No.
Me: Ed, have I ever brought in a cake on Wednesday?
Ed: No.
Me: John, have I ever brought in a cake on Wednesday?
John: No.
Me: Tinh, have I ever brought in a cake on Wednesday?
Tinh: Hell, no.
Me: Up until I’m taken on as a full time position where baking is in my job description, I receive a cost center to which I can charge for your Wednesday cake, or you provide for me vacation days such that Wednesday is the first day of the week, you shall never see a Wednesday cake.
Coworker: Ok.  I come back tomorrow.
