Companies make absolute fucking bank over "small insignificant" things like this.
Yes it's only 50¢ but how many people every day think to themselves "oh it's just 50 cents"
Then add that up over the whole year, for every location.
It quickly becomes much more than the "insignificant" 50¢.
And they know you are more likely to pay it and keep quiet than argue or simply not buy the item.
Sure it's "just 50 cents" for you, but for the company, by the end of the day it's more than most make in a year.
Note: actual dollar amounts company-wide for garlic cups is not something I happen to know, but based on how much I've seen them slinging cups into the boxes while I wait for my pizza, it's gotta be a lot.
Companies sure so have a lot of "glitches" and "technical difficulties" when they're introducing controversial features that forces it on a group of people, only to be nearly immediately removed with all kinds of excuses..... And then the feature is forced for everyone within a few months.
Almost like it's NOT unintentional, they're NOT experiencing technical difficulties, and they're actually just testing the waters before diving in, with neatly 0 intent to pull back unless the consumers put upenoigh of a fuss the company execs get scared.
