Lately I have been noticing when signs are comically in error.
I have one that, unfortunately is not up to snuff with resolution.
I will put it here and describe, even though that will not bring the irony as well.
It is a photo with a couple of no smoking signs (which you can see as well as the ash tray), but the one that is blurred is a sign saying “Smoking Area” and requisite disclaimer.
The other is self explanatory, although it is also not a quality shot.
