Grudges shouldnt hold them as only make you bitter so not worth it I myself never had a grudge held against me by any controller as you go to work to work suck it up and get on with it This aint a cowboy movie where someone steals some cattle and you get a posse up of the likes of john wayne sid james(carry on cowboy)kirk dougals (ok coral)etc So Ask yourself not what your controller can do for you but what you can do for your controller and then be living the days of Happy Days like the Fonz
