Tale of 2 flights-Service
 

I flew yesterday CLE-FLL via EWR. Both flights full 737-800's. Note is was very hot in both CLE and EWR. First leg to EWR as I boarded to sit in my baulkhead seat 7D FA was doing a pre-takeoff drink service for those in F. Also during the flight I noticed as I get a good view from 7D the FA in F
was coming around during the entire flight giving passengers service and getting multiple drinks.
Next flight 1042 EWR-FLL I was upgraded and sitting in 1A. It was again very hot, but no pre-takeoff drink service was offered. Also during the
flight due to some weather drink service even in F did not start till almost 1.30 into the flight. Also the FA only came one time for drinks, no second rounds.

Yes, the service offered varies based on the crew and flight conditions.

I don't think I'm alone in stating it should not differ - at least by such a wide variance. Actually, I'm pretty sure the VP of Inflight would agree with me.

PD drinks should be consistent - every flight, every time - unless there is a late boarding/departure crunch or late catering. Inflight service should be consistent - every flight, every time - unless there is a safety issue with FAs moving around due to turbulence.

The crew has been trained to deliver a specific level of service in each cabin based on the length of the flight and the catering being offered.
