There are people who would rather die than change.
You are one of them.
Consider yourself a member of the order of Shakers.
I'd be a proud member. I'm aware of the Shakers, know that their furniture style is reproduced, and when I'd drive from my home, taking Route 20 in New York State to drive to Albany, I passed the Shaker Museum that sits just off that Route. I know I had Quakers on my mother's side of the family that lived in Prince Edward County, Ontario, Canada, so perhaps those genes live on in me. I was brought up Catholic, but I don't go to church.
I'll be 78 next month, so I grew up in simpler times, and enjoyed those less-complicated days. People who never lived in those days have no concept of how it was. As technology has advanced, so has the criminal entities that take advantage of it, and leave a trail of victims.
I loved the story of putting in the buzzer to resolve the problem. You accommodated your clients, which was the goal. Good for you.
