He was asking for advice about mangrove monitors so I gave him advice on them. I never recommended one to himI think it would be better to give him sound advice so that he knows what he is doing, since he seems to want one
You can't "tame" a lizard, but then again if we are going to argue semantics you are wrong in your wording also- monitors do not display complex emotions like "trust." They are intelligent enough to learn, over time, that the large creature that feeds them, opens their cage, etc. is not going to hurt them and in that regard they will "trust" you and act like they are "tame" although it is really nothing other than the fact that they have gotten used to human contact enough that they no longer see us as a danger to themselves unless we act in a manner that would cause them to fear us.
I don't know why you feel the need to argue about my "pet shop owner" answer since it is sound advice... Unless you'd recommend him getting a wild caught adult instead of a wild caught babyI don't know how many mangroves you've had but I will say that 100% of the babies I have cared for have acclimated to captivity much much better and sooner than any of the adults I've had.
