I was on QF32 (SIN-SYD) yesterday and was pretty excited to be flying on the A380 again after a great experience outbound on QF31 (SYD-SIN) a couple of weeks ago. The cabin crew on both legs were warm and friendly and the A380 is just a fabulous aircraft even in economy with AVOD and large IFE screens. Food was pretty good on both legs with a solid main meal but a slightly disappointing second service offering of a small bread roll. However, the big difference between the flights (aside from the "re-timing" of QF32 from 9:30AM to 10AM) was the cleanliness of the cabin. Outbound the aircraft was spotless but on the return leg my seat not only had crumbs (over which the cleaning crew plopped the blanket and pillow) but the IFE controller had a bonus mushroom on it! Not the best experience and something you would not expect on the Qantas flagship so I've written in and let them know.
