I write checks still, for lots of things; and it has made me very nervous before to hear people behind me sighing or complaining to the person they are with. I have a debit card; but still want that written proof for some things, and it is my right. The world has become very fast and people get so used to it, they lose their ability to be patient.
I am not trying to make anyone feel uncomfortable; just expressing the feelings on the other side of the story.
