Three plus hour flight in First (now branded as business per app) no pre departure drink, no water bottle or box, one beverage service and snack basket handed out once by lead flight attendant. Then she sat on her seat and played on her phone for rest of flight. Watched other first class passengers walk to galley area with their dirty glasses and request an additional drink. Self service it seems! Noticed that the rest of the plane got one drink as well. Wasn't even a red eye flight. Will fly Delta in future on this route.
