I delivered "The Philadelphia Bulletin" while in 7th and 8th grade (1975-1977). It was an afternoon paper, and it cost $1.40 a week. So my most common tip was to get $2 and a 'keep the change.' I rode my bike and could nail those papers on a doorstep at 20 yards without stopping the bike. The best part of the route was delivering to a local apartment bldg. I could not only knock off 1/3rd of my route with ONE stop, but in the winters, it was toasty warm in there. And the elderly people who lived there like my company. They'd give me hot chocolate in the winters or iced tea in the summers and want me to sit and listen to their stories. Sadly, for some, I was often their only interaction w/the outside world all week......
