Topper sometimes.
The cake decoration is always done by the baker except in rare situations.
What if they want rainbow frosting and the baker only stocks a few colors?
Seriously what are you talking about? Do you know what the law says? There's no requirement for the bakery to stock anything different than it normally would, there's no requirement for them to buy special toppers, there's no requirement for them to buy special frosting, there's no requirement for them to do anything else like that.
All it means... the only thing it means...... is that if you sell wedding cakes that you must be willing to offer the same wedding cakes to everyone.
