Here’s a story of a parking spot, an argument, a baseball bat, and an off duty NYPD cop convicted of murder.

Loach, we know that this isn’t you, but you see why cops have bad reputations? Why don’t you go out and save a cat from a tree, get some press for it, and try to square things off for your profession? 
I pretty much ignore such signs and nothing bad has ever happened. Note- I do NOT ignore/park in Handicapped Only spaces, of course!
Dennis Leary, I’m an Asshole
More information on the enforceability of things like pregnant parking can be found in this thread; see its posts #16, 19, and 26.
Did you check both the plates and for a hanging tag? My father has an invisible disability that makes walking painful. He uses the mirror tag so that he can take it from vehicle to vehicle.
Well i saw this guy at my work who has a permanent placard on his plate. He has a speech impediment. What does that have to do with getting a closer spot?
Perhaps he has another disability you don’t know about.
No such thing here. You get a prominent permit that must be in display in your vehicle. He had nothing.
Then again, I get ticked at the jerks who don’t return their shopping carts. You’re a dipshit of you can’t take 30 seconds to push your cart somewhere so that you don’t inconvenience the next shopper who tries to park. What the fuck are you thinking?
That I’m helping to keep the shopping cart kid employed. 
Never ceases to amaze me the number of people, even the ones who are intelligent enough that this board’s content interests them, who are so anti-social that they feel they have the right to do as they damn please and the hell with the rules. Really a sad commentary on our society. IMHO.
So I’m on the shuttle train at the Cincinnati airport and I’ve managed to score one of the seats. A young woman boards and says that she’s pregnant and could she please sit. I reflexively surrender my seat and then ask her how far along she is. She says, “About 15 minutes, and am I ever tired.”

Or perhaps they’re simply not content with being unfairly discriminated against
She’s not getting pregnant from that.
I think even if it isn’t legally enforcable, I think it is an asshole thing to do, park in another businesses parking space. IME, it is always the quickie shops that are fighting to allow their customers to run in and out.
It sucks when you know you just have take more time walking to the shop than it would take to conduct business in the shop, especially when it is because an entitled jerk took a spot.
To those that park in the pregnancy spots? May you be cursed with an altered center of gravity, sciatica and loose tendons for just enough time for you not to readily be able to adapt to it. Is it really that terrible for a few businesses to take it into consideration?
I worked at a business that was in a shopping center that was so popular that our patrons would take up every spot in the parking lot during the few hours we were open. The other businesses (a clothing store, a bar, an insurance agent and two smal restaurants) complained to my boss and to the owner of the strip center. After some negotiation, the parking lot was divided up and the boss agreed to put up signs and hire a security guard to make sure that people were parking in the right area. If people didn’t head the signs or listen to the security guard, they were towed.
If they feel that way, then they can either complain to the owners, or not shop there.
Besides, if special parking spaces are considered “unfairly discriminating”, that’s pretty sad. If the store owner wants to give expectant mothers a closer space, that’s their choice.
Or park there.
Just as it’s their patron’s choice to ignore these discriminatory signs.
I was on the edge of homicide when a woman, whose car had a handicapped sticker, slipped into a non-handicapped space I had been waiting for – the last non-handicapped space in the lot. There were at least two handicapped spots open about two spaces away.
She could have parked in such a way so that we both had parking. But, no …
