What does it all mean? You're sitting there in a diner munching happily away on your onion rings and this pops up. It's a sign, I'm sure, but of what? The circle of life? Infinity? Too much grease in the deep fryer?
If you study numerology (I don't) it seems that the number 8 is a sign of prosperity and balance. Harmony and abundance. But all of those need to be achieved through hard work and perseverance, which the number 8 gives rise to by being a continuous loop.
So, am I just supposed to stop noodling around here and get back to work or what?
(BTW, we showed this to the waitress and she went and got the cook and we all had a ponder as to the meaning!)
