I actually had to look it up. The word is inclement. According to dictionary.com, it means "Severe, rough, or harsh; stormy." Inclimate might work if you just say it, but don't write it.
When the sign disappeared for a few days, I thought it might be out for repairs. Turns out, they were just changing the name of the establishment (and telephone number). The sign-maker never caught his mistake...
I always learned that when part of a text was in quotes, it meant it wasn't really true, but was what someone said/thought was true. In this case, one would assume there are not really hardwood floors, but something else that could be mistaken for hardwood floors. Unfortunately, this doesn't really attract me to want to live there. Additionally, off-street parking in quotes might mean parking on the sidewalk?
It seems to be hand-painted and was found in a bin with some other similar hand-painted signs, each containing a year between 1975 and 1979. Does this mean anything?
