Sales negotiation
A salesperson arrives at a meeting, settles in calmly, and lays their documents out broadly across the table rather than staying hunched at the edge. This calm occupation of the working surface projects assurance and establishes a relationship of equals with the buyer.
Occupy your share of the working surface calmly and with measured amplitude; spatial ease reads as legitimacy.
Establishes a status of equal; the assurance perceived lends credibility to the offer.
Excessive occupation (encroaching on the other's space, over-wide gestures) reads as arrogance and puts the buyer on the defensive.
