Perhaps those people who suffer rejecting-unpleasantness should do their own therapy where they go around rejecting people's requests!
I may not like it, but people regularly approach to ask for money, to sign up for a recurring donation, to sign a petition, to give a flyer, to sell a CD of music (yes, even in modern times), or to give a product sample. I may also get photographed by a street photographer. A small request that can help someone with their problems looks relatively mild compared to most of these other actions.
This could be discouraging towards “new” employees though. Maybe they should walk around and learn getting rejected… oh well
