This review isn't about Trader Joe's as an entire company, only this location. I love many of their private label items so I'm at this location at least once a week even though it's 8 miles from my house.
What really bugs me about this store is that I see something in the dairy section that is out of code every single time I go there. Once I pointed out to an employee that some yogurt on the shelf had expired two days ago, and he reacted as if I insulted him personally.
For the cashiers, the customer service is about 50/50. There are a few unfriendly folks with a bit of attitude, but there are plently who go out of their way to strike up a conversation and are very helpful.
