My recent experience with Costco, anyone else?

I’ve been a Costco member since 2005, and my folks have shopped there since the Price Club days. We buy most of our groceries, appliances, and even clothes from Costco. A few months ago, we bought a dishwasher with missing parts (side securing latches), and returning it was a hassle. I thought it was just bad luck, but I had the same experience returning clothes (with tags on) a few weeks ago. My husband also has noticed that the exit staff now carefully count and check our items, and the staff often seem agitated, similar to what you might see at Walmart. The quality of fresh produce has also declined, which, combined with everything else, makes shopping there less enjoyable. Has management changed recently or something?
