No, it's signaling that you're wasting time and need to move on.
Many situations cannot be resolved until you convince the other party that their business model or position or assumptions are wrong. Walking away is the only way to do that because it triggers escalation.
I had s sitstuiin recently where the account team couldn't get a term that we needed. We basically told them to go away and stopped 2-3 other negotiations. That let our counterparty get the resource he needed (SVP of product X) and balance returned to the force.
Not really, there are some situations where the deal is too heavily skewed for it to be favorable for you. In human terms "I'm not willing to pay this much for this". What AI might actually consider bugs would be stuff like politeness or pity (I can't refuse to buy from this small hungry child), basically things external to the actual process of negotiation, but that might have considerable impact on human agents and how they would feel afterwards. (for example giving money to a beggar is a one-way act, but the donor will likely feel good about themselves despite not getting any material gains) Similarly, people might purposefully adjust their tactics depending on the status of who they are negotiating with, making more concessions with family and friends. If the AI just looks at the inherent value of the items, it'll miss things like that.
Walking away is a bug if you consider a single deal - it's always better to get something rather than nothing.
However, if you zoom out and consider the optimal deal-making strategy over multiple deals, then walking away can be a good strategy. For example, a used car salesman would rationally walk away from a deal if they believed it's likely they can sell a car later for a better price.
If you consider multiple deals then you can also consider the concept of your reputation. This is information that other parties may have about you when they enter a negotiation in the future. You may rationally wish to make a sacrifice on a present deal in order to alter your reputation, to improve your outcomes in future detals.
