Yes I have seen the exact same on a couple of recent CE flights. The crew working their socks off but the trolleys aren't configured in anything like the right way for efficient delivery of the service. I understand that sometimes there is also no longer space for a rubbish trolley which makes life even more complicated for the crew.

This was only 5 rows on a 2hour 30min flight - I can't imagine how this would have worked with 12 rows in less time.
