People don't listen well. If in doubt, on a removal, have them spray paint it, or tie a string, or a flag, or something. People sometimes confuse the left for the right. A garden fence may not be 'the fence', only the lot-line fence is 'the fence' or other dum things. Most people just think the pecan is the brown stick with green leaves, much like the oak is the brown stick with green leaves.
Even when you're totally right in the situation, and they are wrong, it still works out better, IMO.
Someone said recently that MacArthur said that instructions can't just be understandable, they have to be not misunderstandable.
Hope it worked out well enough. Did you bring any wood glue?
