I found it rather amazing that something like that could make someone depressed!
You see, everybody is screaming blue murder about LH's declining service, but let me tell you some points from the viewpoint of a guy who does fly a lot professionally and privately, that seem to be in line with what other frequent travellers have mentioned, too:
1. Sandwiches are about the second-to-last thing that comes to my mind when talking about a priority list.
2. Reliability is way up on my list (and not only on mine), to be on time, to have an efficient connecting system, if my flight is late (which is something LH does handle quite well).
3. A halfway clean non-smelling aircraft with F/As who know what they do (which is something LH handles very well, though there are some people on this Forum, who swear any oath, that LH F/As are ugly, old, unpleasant valkyries, that are out to hurt other people).
4. LH gives sandwiches to Business class pax on short-haul domestic services since ages, and it is still the case (I had one yesterday morning on FRA-HAM), though I couldn't care less, actually, as long as they get me to HAM in time. Carriers are in a somewhat unpleasant situation since 9-11, LH loses millions of €s everyday, so they try to lower their cost, and that's just what they do.
I know it's only VfB but I like it!
