Suppose the mall opens at 8am. You're there at ten past eight, watching 25 spaces. Everyone there has only just gone in and won't be back for at least an hour.
Don't hover. Park further away and walk, ya lazy slugs. It'll do you good. Unless you have some medical issue like knee problems or something. And the rest of us should park in the outer bays so the mobility-limited (but not actually disabled) can use the mid-range bays.
