I often had problems getting de-iced at an airport close to New York where anything could happen during de-icing and often did. Procedures were rarely followed.
On one of the flights a cabin crew member called on the interphone and asked if de-icing was finished. It was just that she said she could still see snow and ice on the wing. The FO promptly said they would double check and headed down in to the cabin. Yes, there was snow and ice on the wing. So I asked to be de-iced again.
After that was finished I went down to check. The contamination remained. This resulted in a further request to be de-iced. This time I stood by the overwing exit to watch the de-icing. We finally taxied with a clean wing after a considerable delay.
My wife was on board and had witnessed the whole thing. She began to realise that some of the "horror stories" I had told her had some basis in fact.
We lived to tell the tale!
Excellent CRM from the cabin crew member! I wrote to her line manager commending her for her actions.
