This is going to take some time, so bear with me.
A friend/associate of mine operates a very successful sales training business. I credit his success to the creative and insightful way he communicates complex material. Recently, I received his monthly newsletter that had this interesting bit of information...
""DON'T SPILL YOUR CANDY IN THE LOBBY"
"Imagine - you spend five dollars today on a box of candy at the movies! You can't wait until you get in, so you fumble to open the box and spill most of the candy on the lobby floor before you even get through the doors to your seat. It ends up that you have only a few pieces of candy left to get you through the picture.î Don't you just hate it?"
OK, compelling enough to get my attention and make me keep reading, but what about the 5-second rule? It appears to be my day for dispelling/proving myths (see this post from earlier today) and I found this interesting article which apparently proves that in many instances, the 5-second rule is not a myth but has some grain of truth. Frankly, it looks like a job for Mythbusters
Unfortunately, I think the rule should be applied with descretion... 'cuz, if I drop something on the theater floor, it's going to be there a heck of a lot longer than 5 seconds... which in fact, seems to explain where that primordial goo comes from on cinema floors.
I feel better now.
