It was a couple of years ago and I was very tired but I remember the departures of Bristol airport being one huge shopping precinct complete with endless loud animated perfume ads on big screens. I can't see how that would encourage anyone to buy there, unless the offered to shut-off the volume with a purchase.
Also, the shops were closed as it was nearly midnight. Can't they turn-off the ads when the shutters go down?
I've never been so glad to board an Easyjet flight, even two hours delayed. I watched it coming in on FR24 on my phone and cheered when it came into view.
