I'm afraid that they are not paid to be be "customer service"agents. They have a function which is actually very serious and important to ensure national security
I have also had my bags pulled out a couple of times for no apparent reason, but at the end of the day they are doing their job and if they stop someone who is genuinely bringing something illegal into the country (etc) then it's worth it
I do agree that they could be a little more 'friendly' but I have yet to meet one that is - that's includes in the US and also throughout Europe. Indeed I got my passport checked & stamped when returning to my own country last year. I asked him why and the answer was "because I want to!"
As they say, c'est la vie.............. that's life!
