Oh, you don't need a personal invitation to go to these events, she most likely just saw an ad or picked up a flier somewhere, called and made a reservation. I've done it probably 100 times over the years, so have many people I know. I don't know about Geneva but where I live companies organize these events all the time, to acquire new clients and to promote their goods and services, or to celebrate opening/reopening. Usually the way it works is - a presenter gives a lecture outlining goods or services and the company's achievements (I should call it a sales presentation; in case of medical companies attendees might get a sample treatment), followed by lunch or dinner or, as in Anna's case, appetizers, and the presenter (or assistants, depending on the company) goes around collecting attendees' names and contact info and booking appointments while the guests mingle over food (which was the segment of the event that Anna documented, she didn't document the presentation). The events I've attended had been organized by all sorts of companies - investment management firms, plastic surgeons/dermatologists/dental offices, art galleries; the last one I attended recently was organized by a cremation company (morbid but inevitable). You don't dress up to these events, it's casual or, if you prefer, dressy casual. It looks like the event Anna attended was organized by Lamborghini dealership - maybe to celebrate expansion or a new fleet of cars? Maybe a French speaker can check Geneva Lamborghini dealership website, see if any info on this event can be found and report back to us? I suspect the lady in a blue blouse was one of the assistants working the event - she gives off those vibes.
