This "we run out of bkfast" has happen to me on several flights with CX. Usually when sitting in the bulkhead as they reverse the serving order from front to back for dinner to back to front for bkfast. By the time they reached the first road they would have run out of Y bkfast and offered a small pizza from the C bar.
I can recall SK Christmas's flights where the side panels where decorated with small xmass crown's every 2 rows or so... but that of course was on an MD87 or 82 with the 1990's SK. I doubt this is done anymore... it gave a very nice feeling...
