Lots of the employees are very rude at this Simi Valley Costco. Almost every time I go I'm approached by a manager to upgrade my membership to the executive membership and when I tell them I'm not interested they continue to asked and I finally have to just walk away from them. There is also a young man there named Chris is extremely rube.

This is a good Costco, much better than heading to the valley. Of course, as in any other Costco, the lines tend to get long, but the staff is friendly and they do their best to get you thru the line as quick as possible.
