Where the concept of privacy doesn’t exist

So, there I was in an airport lounge, sitting quietly in one corner, minding my own business. My husband, who was travelling in a wheelchair, wanted some water so I went to the buffet counter to get it. Barely had I reached into the fridge, than a voice behind me said, “Excuse me.” I turned around, thinking it was a staff member offering assistance. But no, it was a complete stranger, smiling brightly at me. “Yes,” I asked.
