I noticed this "No Smoking" sign in one of the men's restrooms at the City Market tonight:

A "No Smoking" sign is of course a perfectly normal thing to see in a restroom. What cracked me up, however, was what I noticed on closer inspection:

This of course led me to a thought:

How would a blind person know to feel for a sign there?

Before I could think that through, however, my pondering was interrupted by a terrifying/amusing and somewhat offensive thought:

A blind person attempting to use one of these urinals

Now I know why public restrooms always have a drain on the floor. :)

(My apologies to any blind person who reads this has this read to them.
