Ok, so how about the guy who owns your airline? Would you say the same to him? I think you might be out of a job. And if all your workmates had the same attitude you would all be out of a job.
It's a fact that your airline wouldn't exist for long if you didn't offer good customer service. It would however exist if it had poor safety trained cabin crew. Because very few people, if any, would ever know that.
One airline in the US had a problem with people like you who didn't realise the value of the customer and so the owner of the company devised a great way of showing his staff how important customers were. On every cabin crew employee pay cheque, he had a counter signature by a random passenger who was flying on his airline. I think that's a great way of getting the message across.
I don't dispute at all that you are extremely well trained and emergency procedures are second nature to you when needed and I'm sure you can save lives with your training. As a passenger though I'm more worried about hijack than crashing. So if you were to tell me you were there primarily to pre-empt any hijack or terrorist situation then that would be different. Don't you think more emphasis should be put onto this rather than crash procedures? Things have definitely changed and with every crash, more is learnt about aircraft safety and things get better. Perhaps the people in charge of training should think about this. Also First Aid. There's a real problem that I'm sure you deal with on a regular basis. Do you have enough training in that?
