Company policy to take cabin crew reports seriously, so I got the aircraft de-iced so as not to undermine cabin crews confidence in reporting. Cost the company a "pretty penny" but hey how far do you take training. Yes I know I could of just told them it was OK, but suspect that would have undermined their confidence and would have resulted in them writing it up, which I suspect their managers would have taken further, with all that would have entailed.
At least in the US takeoff with ice anywhere on the upper surface of the wing is prohibited. In my 330 training it was emphasized that ice could form on the upper surface of the wings over the tanks and deicing would be required without exception.
