Yeah but what’s the alternative? Things are expensive, you’ve got to eat. I have to purchase things even if it’s affected by shrinkflation.
Luckily, most places that claim to serve local food are just lying.
And anyway, remarks that are flip about changing consumer behaviors are beyond useless, for ignoring all of the complexity and difficulty in pulling it off. Or are you really giving advice to this educated and privileged audience that doesn't need to hear it because they already know and can?
To the other ones, well, just try replacing them.
Buy a different brand?
Eat something else?
