I think this young woman did a good job. Having worked in retail from age 14 and tried to be really helpful to everyone I served, even running from counter to counter to serve the same person on a memorable occasion because we were short staffed..., I would have been crushed to have caused the sort of reaction described by the OP. Now in my over 70's and, like so many people, have just come through the worst 2 years of my life, I welcome kindnesses when shopping because I have lost most of my confidence as a result and would not have taken offence by this young girl's efforts...but we are all different.
Did you think you were poor growing up?
Why on earth would anyone plant.....
