prob gonna delete this one. okay so contrary to popular belief, you should never attempt this with self checkout!! You put your other items in a separate bag, and then put it on your shoulder while you purchase the rest of your stuff at regular checkout, as a former cashier i assure you they dgaf.
a lot of people don't realize that whole foods has a robust nationwide mutual aid program for giving free goods to community members like you. when you pay for your groceries, instead of going to a cashier, you simply go to the area called "self-checkout" and you're actually able to bag your own items. that means less work for the workers and gives you a little more autonomy in your shopping experience. i usually end up saving a lot of money this way too!
