Whilst we should definitely treat every negative as an objection in the first instance be mindful that we should be seeking to qualify whether we are dealing with an objection (which we can work around) or a condition (which we need to work with).  If you establish that what you are dealing with is in fact a condition, then don’t force the issue too much – it irritates people and potentially burns bridges.  Equally this doesn’t mean that you won’t be able to arrive at the outcome that you wanted but we’ll need to look at other variables to get the deal done.
