Just saw this in a job advert: "My client who are part of one of the largest communication groups' in the world".
Never seen this before- maybe they think that saying "group's" is in actually wrong, but think they just have to get that apostrophe in for some reason? They go on to make the usual mistakes with "incentive's", etc later on, so they're obviously genuinely illiterate, and not just mistyping.
Where will it all end?
