I've also noticed a lot of improvement in customer service and interactions. A whole lot more politeness, courtesy, "Have a great day" type stuff. Is it uniform everywhere? Absolutely not, there's still a fair amount of "I'm a bored teen/college student just trying to earn money over the summer". But I'd say it's about 50/50, and maybe even slightly in favor of the courtesy. Before, it was probably 10/90 (or less, haha).
