I admit, I was mightily annoyed that there were no baggage lockers, so I had to haul my luggage with me constantly, when changing accomodations. It made me very grouchy. But in that case, there was a good reason: people had put bombs in baggage lockers. Sherm kidded me about my resemblence to the "Bomb Girl" who was front page news, and we wondered if I'd be detained for questioning at any checkpoints. (I never was. I guess the lack of Irish accent made me less suspect.)
While we were in London, they blew up the lobby of one of the major hotels. I think it was two or three people who died. We were quite happy to be staying at the low-budget fourth-floor walk-up in Chelsea, at that point. We were evacuated from Madame Tussade's due to a bomb threat, though no bomb was found. But everyone accepted that terrorists were out there, and something could happen, but why get upset? And everything was dealt with sensibly and straightforewardly, with realistic precautions, rather than symbolic ones. But then, the Brits had been dealing with this stuff for a while. After all, these were the guys cited in that one guy's response to the London Tube bombing: "I've been blown up by better terrorists than you lot!"
