On my recent several long-haul CX business flights I encountered different responses as far as mid-flight snack was involved.

For example, on CX-100 there was noodle soup available as a snack and I must add that it tasted really great. On the other hand on CX-111 there were only nuts for a snack which was really disappointing. So, what determines the type of a snack that any certain flight gets? Since CX-100 and CX-111 are exactly on the same route then it makes me wonder why one has decent food while the other has something resembling coach product?
