can't wait to buy it with Pullman dollars - Discuss Online

Hey, my cousin started a small business making cricket protein bars. They did taste good, but they absolutely were not for the poor.

Much more of a virtue signaling yuppy thing.

Why are they for yuppies?
I was trying to convey that they were an expensive eco food, not a cheap protein alternative.
