First Capital Connect issues passenger etiquette guide
A rail firm has issued a cartoon guide to "train etiquette", asking
passengers not to assume fellow travellers share their food and music
tastes.
Its adverts include slogans such as "don't assume they share your taste for kebabs and dubstep".
Advertising experts claim humour is a good way to "cut through" to people.
Good effort!
But one, small, tiny, almost infinitesimal, but none the less significant, niggle...
Sigh... what precisely is wrong with the correct term 'railway etiquette'?
