I assume you're looking for bigger companies. I've had plenty of great experiences with local companies where the person is likely the owner. And I assume you're looking for consistency too - almost every company I've had more than just a couple of interactions with has had at least one person that did their job well from a customer service standpoint.

Here are the most consistent ones though from my experience:

Chick-fil-A, especially when you go inside. And it's not just one - it's most of the ones I've visited. Every now and then you'll get an employee working the drive through that's not exactly pleasant, but still way above the average for fast food.

Publix, a regional southeastern grocery store. Every cashier is very nice and pleasant, the stores are clean and well lit, the baggers are always there to help you load up.

Amazon, the best customer service is not ever needing customer service. Any time I've had a problem it has been because I misread or misunderstood the product description, and there has never been a problem sending anything back.

Fun fact: Publix is the largest majority employee owned company in the US.
