Autoglide said: imaging going to Sainsbury's and they charged you to park
J Sainsbury's in Wilmslow does just that, and won't even refund you at the till with a receipt. It's more common than you think.
While we're imagining stuff, can you imagine how any airport would look if parking was cheap or even free? Picker uppers would never get within a mile of the place, because the other picker uppers would get there early to "make a day of it" and do a bit of plane spotting before they collect and go home, although the passengers will probably have driven in the first place, and parked free for a fortnight.
Sad though it is, there has to be a charge to regulate the supply of a limited commodity in the face of excess demand. Simple economics. Not that different from the locos putting their prices up on high-demand flights. In fact it's exactly the same, but no-one complains about that, do they?
