I would never worry about whether or not I received a thank you note at a funeral.
In my area it's the norm to send flowers or give money at a funeral. It's useuly used to offset funeral costs, help the family or donated to a charity in the deceased name. When my brother passed away suddenly last year my mother and I wrote thank you notes for any money, flowers, food, cards or persons who attended his funeral.
Again, I would never expect the same or pass judgement on those who didn't do what we did.
