Rudeness in hostility is in how you state your position. Having a position (that you dislike and won't participate in a corporate sales funnel is always OK, and it's always OK to politely express that to representatives of the corporation. Even if they happen to be employees of the franchise owner, they're wearing the uniform and promoting the brand, rather than representing 'local burger restaurant.' Of course, you can just not eat there at all (I don't) but in that case no communication is taking place. Many people are OK with McDonalds' food offerings but not with their invasive app marketing.

Trust me, no communication is happening in either situation. Your complaint is not being run up the corporate ladder. All you're doing is making someone's day a bit worse in order to get some fleeting feeling of self-satisfaction for voicing your opinion. You're of course free to be that person, but the rest of us are free to judge you for it.

I do not trust you, because I have been a food service worker and actually know what I'm talking about. A customer expressing a preference has never bothered me if they weren't rude about it. If it happens often enough it does get passed on, even though the individual impact of any counter conversation is low. You are trying to turn normal amicable commercial interactions into some kind of moral purity test.

> I have been a food service worker and actually know what I'm talking about.

Same here.

> A customer expressing a preference has never bothered me if they weren't rude about it.

A lot of people are seemingly skipping over OP describing their behavior as creating a “hostile atmosphere”. That is inherently rude.

> If it happens often enough it does get passed on

But we aren’t talking about just telling your manager. There are so many layers of management and bureaucracy with larger corporations, especially ones with a structure like McDonalds’ franchise model, that these complaints will not make it to the decision makers.

In the modern corporate world that leadership has entirely insulated itself from customer feedback - if it was plausible to voice your opinion through more appropriate channels I'd advocate for that but many companies have purposefully shut those channels down.

What is the better option to pass along that message than modestly increasing retraining costs for that position?

I treat service workers with respect, personally, but I am struggling to see what other venues of communication are still available.

1) Stop using the service.

2) Directly email them anyone who might have some say in the matter.

3) Make public posts on social media about your position.

You still may not get heard, but all of these have better odds than complaining to the front-line service workers.

Like I said in my other comment, this is missing the point. This approach won’t be effective. Nothing is actually being communicated to the people making decisions. The difficulty in finding another more effective approach doesn’t change that fact. If you feel passionate about this issue, you should try some of the suggestions by the other commenter.

FALSE.

In today's economy and politics of normalized and systemic dark pattern enshittification, fomenting discord toward the turtles all the way down is a responsible civic duty of a disgruntled public captured and corralled by corporate monopolies with no exits.
