Here's one-- Since you're just starting out, how about you give me a 3 tiered-fondant-covered-modeling-chocolate-figure-toppered-6-flavored-torted cake for my daughter's bridal shower..in 2 days. It'll be good for you and give you lots of exposure.
How kind of you to think of me but I'd rather GIVE you a poke in the eye. That'd work better for my schedule.
I got that too once! Just laughed it off to show them how ridiculous that is ' ha ha your so funny!'
