Does anyone remember back in the 80's (and/or 90's?) when the golf carts had an automated announcement on a loop? "ding ding boop bop ... an American Airlines passenger service vehicle is approaching ... please step aside ... ding ding boop bop". I certainly felt for the people that worked in the airport during that era having to hear that all day, day in and day out. Today, I guess it would be akin to the welcome messages from the Dallas / FW mayors, I'm sure the airport workers hear that in their sleep.
