As I recall, the flight deck extinguisher on the Bus is in pretty close proximity to the FO, anyone else care to confirm?
Crew being praised all round, except for one bogan on the radio inferring that the cabin crew were panicky, making a crude comment about laundry...
I'm sure they all acted professionally, having experienced a lav fire warning myself (turned out to be a false alarm thankfully) it does get the adrenaline going, but I'm sure that's all he would have observed... passengers tend to get alarmed when the FAs suddenly get very alert and move quickly anywhere in the cabin... wouldn't call that panicking though!
