I was recently in Texas eating at a Denny's restaurant and I see two Flying J roadside assistance employees walk in and get a table. They are wearing dark blue coveralls with reflective yellow safety stripes. Both of their coveralls are dirty and greasy from changing blown tires on stranded 18 wheelers needing a tire replaced on the side of the highway. I told my waitress to put their orders on my bill. When it came time to pay.... the waitress told them that someone had already paid for their breakfast and they thought she was kidding around. Ever buy lunch for a stranger ? I do respect hard working folks that do a difficult and dangerous job.
