We're so polite in this country, at least on the surface, that even obliviously functional signage feels the need to say please and thank you.
."Please give up this seat for the elderly, pregnant and those with children." No, not please, just fucking do it you animal.
."Virgin Trains thanks our customers for not smoking on this service." Why? Will you thank me for not wiping shit on my ticket before presenting it for inspection?
."Please push" - saw this one on a door today. Why does the person who made the sign give a fuck if I go through the door or not? Just tell me to push ffs.
Where's the line here?
