Geoff, whinging allowed by a very large majority on this board, let it worry you not.
As for thanks we show our age, the days of thank you, so sorry, can I help are long over as I have found on more than a few occasions when holding a door open for some one to be told I can hold my own B#'=#@--@# doors open, I smile say my pleasure and walk away wishing I had let the door slam back on them. Second thoughts that could be what they want in this sue for a broken finger nail age.
We give our advice, take it or leave it, experience should count but rarely does, that is not our loss, I smile when the old question comes up, "is there an easy way to garden"? Nope.
Frank.
