You think people working at a multibillion dollar grocery chain give a crap about your 14¢ round-up? It’s implied this is not some “family owned” small store.

Do you think anyone keeps grocery receipts at tax time to claim the $5 write off over the year with 30 receipt’s worth of round-ups?

The meme is essentially true. A big corp is asking a nobody who is probably trying to save some cash to give a billion dollar operation money so the Big Corp gets the brownie points for the donation. They don’t give a shit about you other than “Big Grocer & ‘customers’” donate $$$.

The only two points you made that I agree with are “just say no” if you don’t want to, and donate if you like the good feels. Just make sure Big Grocery is donating to a charity that is decent and doesn’t soak up most of the $ in admin costs.
