IMO, he's thinking that anyone with a disability is incapable of working, so they'll be out during the day getting things done while the rest of us are working 9-5.

Obviously not the case, and people with disabilities who are eligible for a disabled placard, are normal people, many of whom have jobs.

Because disabled people obviously only go to work, going out for fun is only for able bodied people.

Daniel is obviously thinking that disabled people turn into giant, ferocious wolves that will prowl the city streets for their insatiable desire for human flesh when the full moon rises and he doesn't think that means they should be able to get into CVS faster than him when he has shampoo to buy.

They seem to build out the number of handicapped spots for the peak crowd amount, which makes sense. If I'm at Home Depot and it's 8PM, and there are maybe a dozen cars in the lot I could maybe see making a few spots handicap only during certain times?

The flip side is that it's only a few more steps for me. I'll survive

It’s poor logic. He’s assuming disabled people can’t walk and therefore can’t do anything so they have no reason to be out of the house except for work.

My attempt:

People with disabilities are obviously never outdoors themselves without an employed health worker. Outside of the normal work hours (9-17), we can't expect any health workers to be taking diabled patients outdoors, thus Daniel should be allowed to park there on his way home.
