Funny sign language!

You know the Year of the Goat (this coming Chinese New Year) is nearly upon us... with ads like this one:

A rather stranger sighting is this sign, spotted by Huat:

Cats are NOT allowed to hump dogs here?

How about these signs? How should we interpret them?...

Don't do your "business" here" Don't eat while riding your mini scooter here (and keep your hands on the handlebar)? You can sleep here but not with your head in an upright position (it'll scare the rest of us)?

Don't worry, be happy!...

Finally, here's a poser...

This sign was spotted at a standalone ATM at a hawker centre. So what does it mean?
