yes, the 'of' instead of 'have' in this context grinds with me too.Did it really say "may of" ?!?! It annoys me when people make that mistake on forums but I can forgive that, but for a company to make that mistake in a press release is unforgivable! Can they not even be bothered to proof read? It just shows them up to lack intelligence IMO.
And what does "guaranteed seat" mean? Ah yes, that you are not guaranteed travel. Is that what customers want? Strangely enough, no it isn't. You are almost guaranteed travel on the East Coast franchise, as the chances of the train being so full you cannot physically get on are negligible, as you can stand. But the equivalent coach services can turf you away and it could be hours before the next one, which could also send you packing. Only a complete idiot would make the conclusion that coach travel is more convenient for customers on that basis.
Unfortunately, the great unwashed, the British public, are now so ingrained in this grammatical faux-pas I don't think there is any chance of reversing this.
But for a corporate body to have it in their printed literature, whatever next?
disgusted, OF Tubridge Wells!
