Since you've chosen to highlight LH vs SH you might like to consider the fact that on some SH services, the crewing reduction amounts to 25%.
Yes, we have a "simpler" service now, but the fact is, that in some instances this sees us now handing-out more individual items than we did before. Some crew really don't help themselves though .... for instance, in a service where tea/coffee are the only offered options, I'm still hearing crew asking "what would you like to drink?" ... which is a bit too open-ended, and slows things down. Amazingly also, some crew are turning-up for briefings without any awareness of the new service offerings, despite this all being readily available in print and on online.
Most of us (and admittedly, this maybe easier on smaller aircraft) are doing our best to maintain awareness of what's going-on in either cabin, and tryng to be where we are needed, when we are needed.
So far, for me, it's working.
