I’m talking about the more unexpected or personal extras that fall outside the standard menu.
For me, it was the opposite way around, and in the early 80's I served my time as an apprentice painter, 19 years old
One of our regular jobs, was in giving the local sauna and massage place a coat of paint. When the premise was closed, we would begin the work in the public and lounge area, so it was ready for the next day, when the premises opens. The place had around 4 cabins, so one would be closed while were painting this cabin, and then we move on to the others.
Work finished, and this is where it got interesting, as the owner asked myself, and the other lad, do we want a free massage. Even before I stepped into this massage premises, I already knew what goes on in there, but the other lad had no idea
Head to my work place, remove my overalls and return, and have a good shower, and then my massage began. Was offered extra's on the house, but this would be a one of, but future entrance fee would be waived
