Succinct doesn't always = accurate

I saw this sign at a garden nursery on the way to doing a day's volunteering for my cycle club way out woop woop (Aussie for back of beyond)......it's unintentional humour kept me smiling most of the loooong boring day being a corner marshall:

apologies for the appalling quality of the pix...my phone bleached out all of the colour (the sign was a bright yellow) and resulting in mega manipulation having to be applied.
