Lack of refuse bins

I was not able to find a refuse bin at most part of Heathrow Airport. I mentioned this to the staff at the check-in counter and asked her to throw away the wrappings that I had carried in my pocket. She explained that this is due to "security reasons". Frankly, I think that the security people have gone overboard in their measures. While security is important, it has to be practical and sensible and not caused a lot of inconvenience to the public. The real risk has also to be measured.
