Can the Person who performed Shrardh, personally serve food to others who have come for the Shrardh?

Pt. Shri. Khape Vasudevachar

Shrardh

Previous (If Annual Shrardh falls during Mahalaya, can we perform Paksha Shrardha also on that day? Can we perform Paksha Shrardha on any other tithi after the Annual Shrardh is over?)     |     Next (Can a person who has lost one of his parents recently (within 1 year) continue to perform the Annual Shrardh for the other Parent who passed away before 1 year?)
