I was texting with my phone while waiting next to a busy looking entry point at an airport in Canada; I was not going to the US, I was heading back to Europe. An airport person asked me if I have a Nexus. Somewhat absentminded while texting, I said yes I do (my phone was from the Google Nexus line). "Right this way Sir!", and I followed him for 10 meters. And then at that gate entry eventually I pieced it together that my phone was not the Nexus they were looking for, excused myself and went away wondering why air travel seems to make me hypoxic.
