Napoleon Pastries

The Mille-feuille (French pronunciation: [mil fœj], "thousand sheets"), Napoleon (U.S.), vanilla slice, cream slice or custard slice (Commonwealth countries) is a pastry made of several layers of puff pastry alternating with a sweet filling, typically pastry cream, but sometimes whipped cream, or jam. It is usually glazed with icing or fondant in alternating white and brown (chocolate) strips, and combed. The name is also written as "millefeuille" and "mille feuille". From Wikipedia..
OK "thousand Sheets" OK so why do the restaurants now serve "Napoleons" that have 2 honking big slices of puff pastries..with some berries and whipped cream and maybe pastry cream in between? The layers are supposed to be THIN!!! Charlie's Bakery which is now defunct used to make the best Napoleons..thin layers, lots and lots of thin layers of puff pastry with whipped cream in between. Our girl friend one year made a the sort of Napoleon that is now served in restaurants and we we laughed and kidded her for years about that.. we told her she was serving bricks.. Well, lately when I've ordered an Napoleon, that is what I get a couple of "bricks" of puff pastry with berries and cream in between.. guess it's too much trouble any more to make it properly.
