What’s the most pointless thing you’ve ever deliberately spent Platinum on?

I’m not talking about newbie mistakes or falling for scams, but rather those times when you’ve spent plat on something just because you couldn’t be bothered?

I’m currently building our clan dojo, and I spent 1 plat to rush a room to completion rather than waiting the remaining 20 minutes. (For context, I wasn’t in a particular hurry. I definitely had the time to wait, I just didn’t want to).

You ever dropped plat to save yourself an insignificant amount of effort? Bought ferrite from the market? Rushed a cipher blueprint?
