The number 8 is a number like 0 that should look the same if turned upside down – in theory of course. This is where it gets crazy. Gas stations do not use the number 8 that is equal in the bottom as it is in top, therefore it can be put upside down.
I do not like seeing this at all.  I want so bad to pull over into the gas station and tell them that they need to fix their sign because the number 8 is upside down.  The difference is very slim and I don’t think everyone can notice the upside down-ness of it all but I do and that is crazy.  But it’s no where near as crazy as having an 8 that can be upside down.  I mean really!!!! GOSH!
