The baker could always adjust the "tooling charge" depending on what the happy couple drove up in.
Mercedes $20,000
Buick $5,000
Range Rover $40,000
Used Pick-up $3,000
I was thinking more along the lines of the old joke about the woman who was amenable to the proposition of having sex with someone for a million dollars, but was offended when offered ten. If the baker will abandon his religious principles for money, the amount is irrelevant.
