With Ipsos we are all persona non-grata!
Seriously, though, you might want to contact the scheduler on that. It's possible that they do not want airport employees doing those shops. They are also scheduled very far in advance and already taken. It's like the posting stays on the job board just to collect possible shoppers for emergency or future occasions. After many years, I finally got assigned an in-flight shop, the day before I was leaving - for a different airline than I had submitted my itinerary for! Pfft.
