What happens if Brahmins feel disrespected or leave unsatisfied from Brahmin Bhoj?

The Garuda Purana states that if Brahmins leave a Shradh feast unsatisfied or disrespected, the ancestor receives no nourishment from that rite. The soul remains deprived of its Patheya — the spiritual provisions for its onward journey — and suffers hunger and thirst in the subtle realm. The Vishwamitra Smriti adds that if prohibited food was served, or if Brahmins were insulted, the merit of the entire rite is transferred back to the Brahmin rather than reaching the ancestor.
