One of the things I love about Trader Joe's is that every employee is a foodie, and they are all so glad you stopped by. They are genuinely cheerful poeople and they are beyond helpful to me.
Sometimes, I'll stop in there before having a little gathering in my home with no idea of what to serve. The TJ folks will make recommendations, help me pick cheeses and other things, and check me out. It's like a food consult. They do this with real pleasure and enthusiasm.
