I'm exactly the same, I have only ever pressed it once and that was by accident. I just can't bring myself to press it. I know that I should have no qualms about using it, especially as the picture on the button shows someone bringing me a drink, but I just can't. Sorry.

When I want a drink or something, I prefer to wait for one of the stewardesses to walk past and then ask them. And even then I mitigate it by saying 'when you have free time, I'm in no rush'.

I normally travel business long haul and then it's normally on Asian carriers (mostly OZ) so I don't need to wait very long before someone walks past. When I travel short haul economy it's usually for less than two hours, so generally I don't need anything anyway.

Strangely, on the occasions when I travel long haul economy (i.e when I'm paying for the ticket myself and there's no suitable air miles option in J/C) then I find myself far more prepared to press the call button than when I'm in business. Especially when it's on an airline with dreadful service, like KLM where the staff spend most of their time talking with friends / colleagues. However, I haven't yet made the final push to actually press the button; but I've certainly given it serious consideration.

There's probably something psychological going on here, but I have no idea what.
