If you hold Town Hall meetings during Normal Working Hours how can your Working Constituents come to the meeting without missing work?
If you keep scheduling meetings during the normal daily work hours, all you will get at these town hall meetings (and city council meetings) are people who do not work, e.g. Liberals, Trust Fund Babies, Welfare Recipients, Drug Addicts, Free Loaders and Professional Protestors.
In other words, people who don't have real jobs. Make sense?
