Limit the phone access

It may not be the biggest problem human civilisation has encountered, but is not all inclusive rates for mobile phones horribly annoying?

You may sit down on the train or in a bus to peacefully read a book or a newspaper, and it turns out that the person next to you has unlimited minutes on his/her phone, so they go on talking, talking, talking, just to be social with someone at the other end. It does not cost them anything after all.

I'm all for short useless messages like "We are just approaching the station. No, wait, not yet. But we'll soon be there. Just on time." However, when the discussion goes on for 30 minutes or more, it is torture. Sometimes what you eavesdrop is not even interesting enough to publish to the world on your blog.
