That cashier gossip was ugly and uncalled for.
I work at a Target in TX, and we have cashiers and other store employees on foodstamps. These are folks will full availability, willing to work whenever, but are only scheduled unpredictable hours on the whims of cost-saving management. We have an elderly cart attendant who buys 1 banana for 35c for lunch with his food stamp card.
I was on foodstamps in 1995 in MT. The deal then was that I had to work "X" amount of hours/month (sorry, I no longer remember the exact amount) If you didn't work the required hours at your job, you could make up for it with volunteer work or job-coaching classes. You were dropped from the foodstamps if you didn't comply with the required hours.
These days I live in the pretty picket fence upper-middle class master planned community. I wasn't trash when I was living in a single wide on foodstamps, any more than I am trash driving my kids to dance class in my minivan today. My co-workers who work their butts off at Target aren't trash either.
There are jerks who are poor. who take take take, and foolish with what has been given to them. But trust me, drive through my master-planned community and you will find lots of entitled monied jerks here too.
Money does not equal class.
