This is an update of my previous review. A lot of the good things are still there, but after 17 visits and counting, a lot of ugliness has reared its head. While this location doesn't necessary harass customers with some of the merchandise (cell phones, product demonstrations, etc.), they have started aggressively harassing customers about their crappy membership upgrade/reward plan. Having been approached before, I looked into the program and realized that the cost/benefit was simply not there for me. I don't really spend a lot of money at Costco. When I was approached by an employee today, I politely declined the service. This employee continued to badger me and follow me as I waited in line and left the store. It was all I could do not to make a scene in response.
Find some better employees, Costco (Marisol is first on the chopping block.), and you might get a star back.
