I have been going to this Costco for ten years and everything has been great except for one person in he the tire department. I've been buying Costco tires for ten years as well. Every time I get Sonny in the tire department, he is the rudest most non friendly person there in all of Costco. I'm always pleasant to him just like everyone else I meet but he is just awful. Just smile once in awhile dude! If you hate working their so much, please get out of customer service and stop making everyone else's life miserable. Every other person in Costco is wonderful.
