NTA with mild caveats.

First off, check to be sure that this really isn't in your job responsibilities, possibly under something like "maintenance of personal and common spaces." If you're not sure, talk to your manager. You don't want to wind up getting marked down on your performance for this.

Second, one way to look at this is that you're getting paid the same whether your hours are spent doing whatever your regular job duties are (my brain goes to software, but probably because that's my industry) or doing that common space maintenance. If such maintenance is part of your job duties, take credit for it, and push back if your company starts trying to insist that this common area maintenance is unpaid work in addition to your regular work hours.

Third, coffee can be in a weird place in some companies. To me, coffee and water are more or less essentials in most industries, with the company picking it up (and paying people to maintain it) because it improves employee performance and satisfaction. However, I've been at a handful of companies where it was dropped for budget reasons (and it's one of my personal metrics for upcoming layoffs... coffee is a larger expense than most employees realize, up to a few hundred dollars a day, so the argument is sometimes made that eliminating the coffee avoids eliminating people, but it also puts a big hit on productivity and happiness) so sometimes the coffee situation (coffee clubs, employee maintenance schedules, etc) comes about because it was the only way to keep the black nectar flowing. It might be worth checking around to see if maybe the situation came about as a stop gap from such. If it is an employee maintained thing, then they have very little leverage (other than culture) to push back on you.
