Grown-up behaviour?

I don't know who is worse - those who smoke in the toilets or those who clipe. The BBC reports:

MPs have been accused of flouting the smoking ban - and even sneaking cigarettes in the Commons toilets.
Although it is not illegal to smoke in the Palace of Westminster, both Houses decided to ban it at the same time as the rest of England, on Sunday.
But Labour's Betty Williams told MPs the ban was "already being abused" and offered to show Commons Leader Harriet Harman where people were smoking.
MPs joined in with cries of "division toilets" and "toilets".

Pathetic.
