I worked as a part-time driver and dispatcher for a large limo company, we got lots of retirees. For most, it wasn't the money so much as it got them out of the house, away from their wives friends, too many "Honey Do" lists, being "volunteered" to chauffeur her friends to doctors' appointments, etc. I knew one cheerfulsalesman behind the gun counter of a chain sporting goods store-"i always wanted to work with guns" "See more of the grandkids than I'd like." etc. One man-a retired lawyer-said he enjoyed the driving, the company used Cadillacs, back them they had a 4 year service life, lots of miles of course.
