Free tip of the day:
If you get the blue one, don't wear it to Best Buy. You may get mistaken for an employee. Of course you'll be able to quickly convince the mistaken customer that you are not an employee by actually being competent and knowing what you're talking about.
If you get the blue one with the checkered sleeves and collar, wear it to Best Buy and tell everyone that the checkers mean you are the boss. Maybe one day, if they work hard enough, they'll be fortunate enough to get checkered sleeves and collars of the own.
