A deal is considered complete when an offer is accepted. Most of the time this should be fairly intuitive. The Sheriff may say, “I will let your bag pass for 5 gold.” If the merchant accepts that offer, then the deal is complete. The merchant must pay the Sheriff the 5 gold and the Sheriff must let their bag pass. An offer is a specific deal proposed. It contains clear and specific conditions, such as, “I will let you pass, if you pay me 5 gold.” The rest of the negotiation is haggling. Until there is a clear offer to accept or reject then everything is still open.
