According to one source, Mayweather told both Pacquiao and Koncz to "stop lying" about signing any contracts. The same eyewitness tells us that Mayweather then informed Pacquiao that he's been told multiple lies. Mayweather explained that "he's been trying to make the fight happen" and chose to stay silent throughout the negotiation process because "I don't entertain bullshyt!"
Another source tells us that Pacquiao was "on hush mode", speechless as Mayweather repeated, "stop lying," and asked him "what contract" he signed. As Mayweather reiterated to both men that lies are being told, Koncz began stuttering before attempting to lay all the blame on promoter Bob Arum, telling Mayweather that he's only saying what Arum has been telling him. Mayweather then informed both men that it's not professional to lie and "if you're not going to tell the truth, it's best to stay silent."
