Costco Wholesale General Store

There is only one thing I dislike about this Costco. Man who manages/runs the pharmacy is rude to the front desk employees(maybe others also as I can't see their treatment). They can be run off their feet at times and it was one of those times he berated them in fromt of me being the customer. I found this to be embarassing for us both. Today was not the first time I have seen him do this. He should be talked to and if warranted employees shoold be spoken to privately.
