What's the Deal with Trader Joes?

Anyone been to Trader Joes recently? Busy, right? I don't get it.... is it only a Reno thing? Why is Trader Joes ALWAYS crazy full of people? As a consultant, I'm loving my flex time these days - the fact that I can run errands in the middle of the day as opposed to lunchtime, after 5 p.m., or on weekends - it is outstanding! It's liberating to shop and not have to stand in line. But Trader Joes is another world.... no matter what time, no matter the day, it is SLAMMED. What is the deal? I love it there I just can't help but feeling that people are always in my space!
