Yes, I would ask for the miles. You've never checked in at the gate and asked if they might be able to upgrade you? You never tried to negotiate a 'free' case when you purchased a cell phone? You never asked a police officer/meter maid to consider letting you off the hook, even though you weren't 'entitled' to a Get Out of Jail Free card?
If you've never asked for anything you haven't been 'entitled' to, never ever lied or cheated, well, I think we need to get you canonized (and I'm not even Catholic), because you're the real deal. If you have, however, well, gosh darnit, you might just be dragged down to my human level after all.
I'll reserve my right to be judged for when I'm sitting in front of the jury, thanks.
