Seems the pink paper has a backing on it to stiffen it. Left side seems to show the backing, which may be pink cardboard. Given the mounting location, I would expect it to be “floppy” like the “lined” paper without a stiffener.
All of my above to say, I think someone put a “lot” of effort into the pink sign.
What could the motivations of the owner be, if not to make money?
Please add to my list:
Of those, I think a very healthy 401K contribution from the employer to the employee would be motivating to those already paid well.
Many employees already use the business as a sex pad. (Conference rooms can be gross.)
