Right, I saw two definite mistakes today and one that I'm pretty sure is incorrect but didn't want to mock them until it was confirmed on here
The two definite mistakes were loofer instead of loofah, raison toast (WTF?!) and the one I'm pretty sure was wrong involved an apostrophe (or lack thereof). The sign said "we will beat any competitors price". Now I would have thought that it should read "we will beat any competitor's price". Am I right?
And they were all on professionally printed signs which always makes me shudder. Who proofreads these?!
