where one is bombarded with salespersons hawking free samples of perfume/food/whatever.
This is what pees me off the most! I can just about live with having to walk through the "shopping mall", but I start to get shirty about being approached every 10 meters by sales personnel pushing their products. I am not at an airport to shop. I'm there because I need to get a flight. My message to the sales people is quite simply that they leave me alone
unless I approach them!
