Personne n'a ses clés ?
Does nobody have their keys ? 

"Does nobody have their keys?" strikes me as something that would rarely if ever be said in (American) English. Is there another correct way to translate this? Because this one will be really hard for me to remember because it seems so very strange.

Way back in the dim, distant past when I first started learning French, I think I remember being told that to accept an offer, you say "s'il vous plaît" and to decline, you use 'merci". 

Eg.: Voulez-vous un verre de vin? Oui, s'il vous plaît./ Non, merci. 

I think we also learnt that if you simply replied "merci", it would be understood as declining the offer.

Is this correct?

Dear sir
