Varun Dhawan who is set to bring October this April has gone through an on-set training for his character of a Hotel Management Student in the film. The makers shot the entire sequence with Hotel as a backdrop at reallocation of a five-star hotel in Delhi. Shoojit Sircar who believes in honest and authentic ways of shooting made Varun do everything a real hotel management student goes through, from washing toilets, cleaning dishes, vacuuming, cooking, etc. the actor was required to do all these tasks to pick up the mannerisms of a hotel employee.
Since they were shooting in an actual hotel which hosted a lot of guests from other countries would consider Varun Dhawan as a real employee and order him things to do. The actor was asked to get food orders for the guest and even stopped to request to come for cleaning the room. Varun being in his character completely would even adhere to their requests.
A few times during these practices, Shoojit Sircar would take his shots for the film which Varun was unaware of until he was shown how perfect the shots are.
