I got buzzed on the way to work one morning by an exterminator truck... happened to be the one we used for work, as well as for all of the owner's apartment buildings.
I made a phone call when I got to the office and after identifying who I worked for, asked to speak with a supervisor. I let them know that it wasn't really a good idea to nearly run over their customers.
I got a visit at the office later in the day from the driver and a supervisor with an apology.
