said by perfimage: this payment was at an actual COMCAST office, and again, in person, with cash.
Some folks do not like to pay things by mail and like the opportunity to get it done right there and then with a receipt in hand.
Some people like to pay in cash because they live off of the financial grid. They earn their money under the table in cash; don't have checking accounts or credit cards; and avoid paying anything to Uncle Sam. Not to mention illegal immigrants that don't want the scrutiny checking accounts create.
