IAmA T-Mobile Retail Sales Rep in NY - AMA

I've been working for T-Mobile for the past 2 years, in several stores located in Brooklyn, NY. Have dealt with thousands of customers, and am one of the few reps who will look out for the customer's benefit, rather than my own. You may ask me anything :).

EDIT1 - I should mention that I work for a corporate store, and not an Authorized Dealer.
