Nope. You reluctantly take their money. And make them the cake they deserve for forcing you to make it against your beliefs. Maybe with the “ Jesse Jackson” secret sauce.....
LOL, yes, the sauce. Then take them to the cleaners. Make it look like the chumps were seen coming.
Man, would you eat food that was provided under duress?
"Here's your cake. Keep in mind that I didn't particularly care for you to begin with, then you forced me to incur substantial legal bills, then tried to drive my family out of the business we've held for years, for no other reason than 'you could'. As a result of your actions, my family and I have suffered needless verbal abuse and physical threats from you, and hundreds of people just like you.
So......Bon Appetit!"
I'd not want to be within a mile of a cake like that. It might be ticking.
