I generally loathe salespeople and almost didn't purchase my iPhone yesterday because I couldn't do it online. I walked line the store ready to smack down the first pushy salesperson like an annoying knat. But my sales guy, Chase, completely surprised me. He saw that I knew what I wanted and spared me the upsell bull that makes me want to kill. He even pointed our a discount I was eligible for without me asking about it.
In the end, Chase made this a surprisingly painless deal. I don't know if the entire staff operates line Chase, but I know they should.
