Do you give a donation for a luncheon provided for funeral service attendees by the Church?

The church might tell you what the expected donation is if a funeral luncheon is provided by the parish/church community. In the case of my mother-in-law, we were told $5 per person. For 75 people, this was $350, but we rounded up to $500 since we could afford it, and my in-laws were devout parishioners.
