On arriving at Narita we filled out our customs and immigration forms and joined the queue. Young american lady and partner in front spent the whole time in the queue texting on their phones, even though signs said 'no cameras', and 'no phones'. There was a person checking the forms before you get to the counters, the performance of the young lady when questioned why they hadn't completed the forms was up there with the best DYKWIA that I've seen. Didn't help them though, they still had to stop, go to a bench and fill out forms, meanwhile we happily zoomed past. Some people! or maybe I'm just getting old.
