The Duchess of Sussex is said to have shouted on the phone for 30 minutes. At the other end of the line was a florist selling cut flower arrangements.
According to The Sun, the background to Meghan's anger was a faux pas by the florist: they had leaked details of the bouquet for the royal online.
The source says: "If you worked for them, you were often treated like dirt. More so if you were a dealer of any sort." Most people no longer wanted to work with her - even if she was a prestigious client.
The statement comes at a bad time for Meghan Markle, as she was recently dubbed a "dictator in high heels". The Sun also insists on the accusations that she is unstable and has "psychotic moments".
Markle's team naturally denies these statements - even if they come from former and current employees of the Duchess. Five of her employees described her as the "best boss ever" - after all.
