I think the flippy caps were invented by someone who wanted a simple, foolproof way of IQ checking the workers in the field without a bunch of questions and answers and pens and paper.
I mean, if you can't successfully operation the Stihl Flippy Cap you have to admit it doesn't show to good on the family tree.
Again its a cap. It wasn't FDA approved as a childproofing technique for medicine bottles they are just caps. If the success or failure of your day is somehow going to be directly related to your ability or inability to operate a cap. You probably have bigger life problems that need solving that day.
That is just my opinion, as they say "Don't let the turkeys get you down." Well, I guess the next office mug should show a guy with Stihl Flippy Caps all over him and captioned below that should read, "Don't let the Flippy Caps get your down."
My opinion,
