The clue's in the name.

Continental breakfast - and it would have to include croissants.  And what shape would they be?  Well, croissant-shaped of course - the French word means "crescent". So they're sort of C-shaped.  Unless you buy them from Tesco that is. Apparently, according to the shop, we Brits find that shape difficult to cope with when it comes to buttering and applying our jam.  Can't turn corners, it seems.  So Tesco are starting to sell straight croissants - except of course, if they're straight you can't really call them croissants, can you? Would have to be droites, I reckon.
