Sure, but one thing is:
"Sorry, I cannot accept Discover, do you happen to have another means of payment?"
and another one is:
"Sorry, I cannot accept Discover, and since you presented one of those cards to me once, then you are prevented for the rest of your life to enter these premises again".
In this case, Google is effectively a monopoly/2Big2Fail in advertising. So that remedy is not available or is impractical.
So the issue is not necessarily the behaviors (while reprehensible) but the size of the company.
"Sorry, I cannot accept this bill, and since you presented counterfeit money to me once, then you are prevented for the rest of your life to enter these premises again".
I'm not saying this is right, but I think it's the more apt analogy.
The customer would be arrested by the police, then he/she would be subject to a trial and IF actually found guilty would be sentenced to - say - six months of jail.
If he/she had actually killed someone, then he/she would probably get thirty years or a life sentence.
But here we are still talking about someone who (BTW presumably in good faith) presented the "wrong" piece of paper (a fake bill that he maybe got as change from another restaurant) at the counter of your restaurant to pay the bill, and that was (again presumably) ready to give you another "good" banknote to pay for the service.
I don't think (actually hope) the restaurant owner would call the police for this.
Btw, I'm not saying it's illegal. I'm saying it SHOULD be illegal.
Your local grocery store has far better customer service than this despite razor-thin margins. Payment problems? They’ll work with you. Product is bad? Refund. Sale not ringing through properly? They’ll fix it. Surely Google can afford to have some actual people to help you when you have problems.
But that's explicit and the same for everybody. If you accepted Discover from somebody and not from somebody else, THAT would be discrimination.
Discriminating the credit card somebody is using without telling anybody... well, could still be discrimination. Younger people could be more prone to use an Apple card, couldn't them? Can you demonstrate the "feature" you're discriminating about can't be tied to age, race, gender, etc?

FYI discriminating against people on the basis of age is not illegal when applied to youth, at least in the United States. This is obviously the case as we use age as a gate for many privileges.
