Partially OT, but a somm at a YVR restaurant I went to last night told me that they were out of Laurent Perrier.
Apparently, it is on allocation and he told me that if they placed a bulk order today, that they would not receive the product until sometime in mid-January. Kinda sucks for them with Xmas and New Years menus being set.
But this may help explain why AC also has had issues supplying this to J pax.
