As purely SLF nothing annoys me more than other pax having a moan at some necessary delay. Unfortunately a great many pax are so thick or ignorant that they don't appreciate that de-icing is a very necessary delay and 'diplomatic' or 'professional' language often as not doesn't get through to them. Saying it like it is, as in this case does the job perfectly as well as giving a bit of a laugh to those of us who knew it anyway!
