Buy things on the pancake shop with cake?

So i dont know exactly how this would work, but it would be nice to buy merch from the shop using cake...

I mean cryptocurrency is a currency so why not spend cake to buy cool cake stuff!

i understand the logistical issues and the cake price may need to be higher than just paying with a card, but the option would be nice,

Ofc the price would have to be dynamic as the price of cake changes.

idk if this is a good idea, its my first proposal lol, be nice :P

Thanks for reading!
