I have chronic pain as well. It's horrible! For me, one day may be great and I can return my cart, and others I'm only in the store for emergency purchases.
On bad days, I use my handicapped placard and take a cart from a person who is done with it or has left it near my spot. I need the cart to hold on to and lean over to take the pressure off my discs and take the pain from my legs. When I'm done, I unload and kick the front wheels up over the curb and hold onto the side of the car to make it back to the seat. NO I CAN'T WALK WITHOUT SUPPORT, so taking it into the store or a corral isn't an option. In addition, I choose not to have a bagger help me out because I don't want to waste the time explaining that I need to push the cart rather than him/her because I need to lean on it.
Rather than sitting there judging me, why don't you take a moment to say a little prayer of thanks for not having to deal with issues that might cause you to need to leave a cart?!
The lady in the wheelchair might not be dealing with excrutiating pain. Handicapped, certainly, but maybe not exhausted by pain due to walkiing the aisles of the store. So you can't say that if someone in a wheelchair can return the cart, then everyone should be able to do the same.
I am not stupid, lazy or low class. I am a highly educated, employed and tax paying christian who on the worst days has wondered if paralysis would be better than this horrible pain that medicine sometimes cannot touch.
I am not excusing my actions, as I see nothing wrong with them. Simply hoping that some of the cart nazi's posting here might see that some of us are barely making it through the day and you should thank your lucky stars you don't have to deal with it. I wouldn't wish this pain on my worst enemy
