It has been my infrequent experience that providing service in the galley area is routine and a common expectation. That is across the non-discount airlines when the flight attendants aren't too busy doing something else. So, I would like to presume this was just one of those moments that didn't work out. I hope it is not a shift in standard practices.
Although, the reductions in flight services including the promptness and frequency of beverage and snack service has me a bit skeptical.
I'll wait to see what the airline's reply is about this one. To find out is this a simple anomaly in service or is this someone's new discovery that reduces work for flight attendants AND saves money on food costs? (Hey boss, I have an idea...)
