This situation is sometimes impossible to explain using analogies. Personally, if I was walking along and someone was putting things in my cart and then forcing me to pay for things I don't want, I wouldn't be impressed. Especially if I found out stakeholders were behind it and only doing it to increase personal profits. If they changed store policy and made it so I couldn't fight that abuse, I'd be more angry. They'd force me to buy those tampons I didn't need, fine, then I'd never shop there again.... LOL!

If others were helping you fill the cart, that's a different story and not like anything I was talking about.
