I just wanted to express my gratitude to Jade and Denise for yesterday's Costco checkout. Your assistance was cordial, effective, and greatly appreciated. Thank you, ladies. You represent that store so well. I have to admit, these folks always work really well. Simply being respectful to them will go a long way. You ladies deserve a five star.
