Here is a similar question and aswer session with Guruji

Devotee - “Guruji, to escape awkward situations, we sometimes tell white lies. Also, it is often necessary to lie in order to get others to complete the work that they are doing for us. Is this permissible ?”

Guruji replies – “For those who always speak the truth, tasks may be delayed initially. However, the trust that they build up steadily in the long run will bring them permanent success. Whatever is built on the foundation of Truth is unshakeable. A person who lies may escape immediate retribution, but soon people lose their trust in him. So his success does not last.”
