I totally agree - though most times it's because I have to go and find the front door key!
I found a message to post on my door to stop unwanted callers - it was on a Money expert site:

It has worked a treat as long as it takes me a few minutes to get to the door as by then they have read the sign and disappeared!
What gives you a warm feeling? 🥰
