Urine samples during the Civil War

I received a packet to fill out for re-employment at BMS and my father asked about the drug test portion.  I told him that I took the packet to a local testing center and they sent the results to BMS to which he responsed. “You can just go when you want, and to any location?  In my day, when we had to do a mandatory drug test for our employer we got a cup and a finger pointing to the door, none if this ‘schedule it when you want stuff’, yeesh” I think that may get an award as the world’s oddest “In my day” speech.
