I've actually witnessed this go down. Not this man, but another from my hometown. He'd stand outside of Subway every day asking for money and at the end of each day his wife would pick him up in their brand new Ford F150. Here's the story behind this video:
"I was leaving Walmart when I noticed a man in a wheelchair wearing an eye patch. He was holding a sign that said USMC thanks and God bless. I pulled across the road to let the kids eat. and noticed a car pull up close to me. The wheelchair guy stood up and push his wheelchair across the road at a jog. He talked briefly to the guy that drove the car up, opened the trunk and started taking apart his wheelchair. The second guy grabbed a sign and crossed the road to the same corner."
