Both times I entered the UK, I was asked lots of questions while others breezed through. The second time, my anxious bus driver and many passengers had to wait a long time. Do I just look like a bum? Or does their computer tell them something when they scan my passport? Or do they mistrust Americans?
Spain, Iceland, Netherlands, Canada, Peru, Mexico, Turkey—all just put in their stamp and waved me on. UK is the only place that gave me the third degree.
The second time, it was only me and a Columbian guy out of a whole bus load. The Columbian guy bought his bus ticket AT the ferry entrance, but so did his friend who was not only waved through, but wasn't asked to fill out a "landing card" like the two of us were.
