Parks and Rec sign designer: Math? We don’t need no steenking math!
I can 100% see the following scenario:
Parks & Rec Sign Designer: Hey Manager, the track length is 0.39 miles per lap. How do you want me to do the sign?
Manager: Policy is to use fractions for distances less than a mile, so round it to 1/3. Good enough for rec runners. Let's send it up to Boss for approval.
Boss: We gotta add a 3-lap number too. Otherwise the runners groups take a bite out of my butt at the community meetings.
Manager: So that's gonna look weird since three laps is 1.2 miles and we use decimal miles for anything over 1 mile.
Boss: I'm just headed out for vacation, you all just do it and get the sign up before I get back.
[Boss leaves room]
Manager: Just use decimals for the 3-lap number, and we can blame Boss and/or policy if anyone complains.
[Designer throws an ironic salute]
