Told You Australians are Paranoid

A man was told he could not take his dog Nudge into Adelaide's Thai Spice restaurant after his girlfriend asked if they could bring his guide dog into the restaurant.

The waiter thought that he was asking if gay dogs were allowed and denied them entry to the restaurant, which displayed a "guide dogs welcome" sign- even after they showed the staff a guide dog information card.

The restaurant were ordered by the Equal Opportunity Tribunal (they have these in Oz?) to pay the owner of the dog AU$1 500 (~£903) in compensation, even after a more than reasonable excuse was offered:

"The staff genuinely believed that Nudge was an ordinary pet dog which had been de-sexed to become a gay dog." 

Y-e-s...

Anyway, presuming the burd wasn't blind herself, why did she even ask the question if the sign said it was OK?
