Re her travel job....
(I've not been on here for months but do catch up when I can because, you know, life and work and stuff!)
She worked for a tour operator, she never actually sold holidays to the general public. Agents would call/email asking about availability and pricing etc, she might have suggested a few alternatives but it was the agents who sold the holidays, she would have just confirmed the flights/accommodation etc.
As an ex agent myself, I bet i would have had some communication with her at some point over the years, obviously before TT and the pandemic etc but it does make me wonder!
