Hey, some lady came by looking for you. Since you weren't around I told her to come back later.
Oh. Well I just went to the bathroom. You should have asked her to wait, but that's OK. You didn't know.
Gosh, thanks for not being mad. I sure would hate to lose my job as your assistant. Yep, my job as your assistant is very important.
No problem.
That was sarcasm, ya dumb ass bitch. I'm not your assistant. If I was your assistant, the first thing I'd do is explain the subtleties of sarcasm, then I'd quit.
