Our kitchen areas are by the side of the office entrances, before you get to the desks. This means most people sort themselves out on their way to a meeting or on the way back from the loo or a smoke or something.
There's no culture of rounds, partly because you might not be coming back to your desk immediately when you get a drink. Also, it means people get up from their desks and take a short walk, which is better than not moving from your desk at all. And it's a good place to meet people who don't sit near you and have a brief catch-up, including those who are senior whom you wouldn't actually book a meeting with to chat to. As far as I know, everyone does their own drinks, though senior execs get the option of posh pod coffee in the exec suite.
For important meetings, you can order coffee etc from catering, as long as you have access to a cost centre to charge it to. You still get to serve yourself. It's just it comes out of one of those jug things rather than a kettle.
We also have the option of a couple of coffee bars on site, and people do tend to do rounds for that.
And we have dishwashers which the cleaners fill and empty. I suspect this is because HR reckons it's more cost-effective than dealing with all the staff disputes about messy kitchens.
I don't drink tea or coffee, so this all suits me well.
