I have also been going there because their patio is an excellent place for me to sit in my power chair with my sign hanging from the back. That place is very busy, from both local residents and interstate traffic. Every car that goes there has to pass me at least once. Every car that goes through the drive-thru has to pass me twice. Slowly. I figure one or two sandwiches from that place most days is a small price to pay for what I may gain from it.
Originally my sign was meant specifically for local drivers who repeatedly witnessed me exercising (walking) on a bridge last summer. So a lot of times I go sit on the bridge with my sign in a position for drivers to see. Because they all know what the sign really means.
Here's my sign.
I've actually gotten a lot of positive feedback from people by doing this the last few days (specifically at McDonald's). Demonstrated my Vapcap to a dude yesterday, too.
