There are a few charities in Canada that cold call for donations. They use a tricky prerecorded message from a semi-well-known person

The msg starts with a pause where you say Hello, then the person says Hello, more pause, you saying, Hello? Hello? then the person speaks like it's a real-time call. & it takes a min for you to realize it's a recording.

This is the worst donation solicitation approach EVER. By the time I realize it's a recording I just want to pinch the person and the charity 🙄
