Yup. As a matter of fact the "store manager" at KFC, a very nice young kid, told me that they've had numerous complaints about their handicap parking. He's passed them on to his boss, the regional manager who works for the owner, who lives in Massachusetts and owns a number of KFC franchises. It's hopeless for an individual to matter.
The others, the large and small big-box stores, they're all owned by "holding companies", and the store managers work for regional managers. The site managers really have zero say over any of these issues.
The "owner" of the liquor store, the state of NH, did respond after being hammered in the local media. In short, it would have been bad politics to ignore it.
It's a cultural issue. Nobody cares.
Me? I just go about my day and don't patronize those stores where it's too bad. And if I see someone that's clearly worse off than I am, I try to help them out. If I'm about to pull into the last handicap spot and a car pulls up with a wheelchair on the back, I give it to them and keep looking. It doesn't happen often, but it has happened.
