I did not give much credit to stories like yours until I was in line at checkout to a woman who used food stamps. I went into the parking lot with her and saw her load groceries into a new Cadillac Escalade.
The grocery store where I worked in HS had the policy that bag boys would take your groceries to your car and load them if you wished. The food stamp people would almost always have you take their groceries to their car and load them. I loaded groceries that were paid for with food stamps into new model Cadillacs many times every day. I had a thing I did when bagging groceries for an obese woman with no manners where I would predict foodstamps/Cadillac. I was usually right. Some I remembered because of their filthy “new” cars. The floor in the back seats would be full of McDonalds bags and all the french fries holders and hamburger wrappers. I don’t know how they could tolerate the horrible smell.
