A friend of mine travels to the US from the UK about once every six to eight weeks (he works for a consultancy so goes to see one of their clients regularly). He always flies to the same airport, and every time he arrives, he's detained for 4-5 hours. He's a tremendously relaxed guy so takes it all in his stride, but I think a lot of people in that situation wouldn't have the attitude of 'oh well, it's only my time that's being wasted'.
