Not a regret. More like a blip on my punting radar.
Not asking HK Georgina/Ketty from 121/SS whether extra is on her menu.
No meeting V Shelley from 5 Dock early in her career where she was offering FS to customer with fat wallets (tipped off by a famous ML on this forum). We still had lots of fun though.
On the plus side, gratitude to them for teaching me a life lesson "the answer is always no until you ask"
They have long retired now so wish them nothing but the very best
