Murre, your insistence to follow a rigid customs that are not shared by everyone just shows how arrogant you are and your ignorance of other cultures. Some people counter gifts with reciprocal gifts or favors at another time in the future. It is true that one good turn deserves another but relationships are not a transaction and appreciation can be shown in many ways.

It seems that you are an authoritarian minded person who see all rules as set in stone and that there is no room for more than one culture or variations in custom. This is the mark of a closed minded person.
