Oh wow that is a bummer that the crew wasn't so great. I flew Swiss on 4 segments last year and the crew were great, especially on LX 41 and 42 LAX to ZRH and back. The four of us were traveling to CPH for a cruise. Even though I was sitting next to my 86 year old grandmother, the purser came by frequently to checkup on her. The business class FA's on our aisle even took the time to take out the appetizers and the breakfast mains to show my grandmother before taking her order. And just before landing, the even purser came by and presented my grandmother with a box of the chocolates from the meal service.
I personally thought the nice clean white service ware was very Swiss simple but elegant.
