Apologies, I should have been clearer. 'We' refers to us the lounge users.
When I said survey I didn't mean a document that consisted of multiple pages. Perhaps something very simple.
My thinking is, if you're going to try and advertise products to get my attention, at least make them something I'm interested in. And yes, I'm aware you can't please everyone but if it was a simple "Which would you like to see advertised in the lounges? Food and drink, Technology, Services or Clothing", at least its generic enough for BA to partner with someone.
Like I said originally, I'm not a fan of the in-lounge advertising. If I wanted to shop I'd stroll around T5.
