This case discusses the legal obligation of attending a dinner invitation between friends. Kalai Haldar invited his friend Sheikh to dinner, but Sheikh did not attend due to unknown reasons. Kalai then sued Sheikh for the price of the uneaten food. The court ruled that an invitation to dinner among friends creates a social obligation, not a legal one, so Kalai could not claim compensation. The key lesson is that for a proposal to be legally binding, it must create a clear legal obligation, not a casual social one.
