The Northeastern Illinois farm town I live in will have a marijuana store in July, 2020.

Thanks to the federal government I will not be able to use my credit card to buy marijuana edibles. This is ridiculous but the next President, Mike Bloomberg, will fix the problem.

I looked it up:

"Can I use a credit card to purchase? Probably not. Because marijuana is still illegal at the federal level, most credit card companies don't work with dispensaries or other cannabis-related entities, so you should come prepared with cash."

Cash is obsolete. There is no good reason to have to carry cash.
