The item that stands out for me is:
Clearly, this ought to be “You’re” as in Think you are man enough?”. I hate to see mistakes of this nature. They have gone to the trouble of getting this sign hand-painted, but just because it wasn’t done on a computer with a spellcheck feature, doesn’t mean it can’t be proof-read.
Things are getting worse when it’s considered acceptable to put up signs with mistakes and bad English.
