Gross is said to have been incompetent.As they parted, Franco, who was worried by Hitler’s attitude, decided to emphasise his esteem for him in a typically Spanish manner. He stood up and pressed Hitler’s hand between both of his, and declared, “In spite of what we’ve said, if the day ever comes when Germany really needs me I will be at your side unconditionally and without asking for anything in return.”Gross failed completely to translate this, and so Franco's parting gesture of reconciliation went for nothing. However, Serrano Suñer was actually glad of the interpreter’s gaffe, because he saw it as avoiding another commitment.
