now that I've posted over 15 times, I can post my "website" if folks want to see my cakes. I'm a little embarassed to show y'all, due to the stunning expertise represented here, but oh well. It is what it is.
i would say charge and credit the purchase with a percentage of the tasting fee.
hold all appointments with the cc, with a fee for missed appointments, say $10 to cover your costs, etc...
people will take great advantage of a free tasting and feel free to break appts.
be savvy, be smart and deliver a beautiful cake!
bake first, ask questions later. Oooh food, my favorite!
