Yes there should be a fat tax.
At one time or another each and everyone of us are going to be a victim of second hand fat.
These people go back for seconds, and thirds, while the rest of the homeless in the Bronx are starving. Fat people obstruct views, "hangover" seats when you sit next to them and god forbid if there ever was a fire and they block an exit or escape route cause they are rolling around on the floor like a beached whale trying to get back up.
C'mon guys, do you have to wait for another elevator because 2-3 fat people have exceeded the weight capacity?
275 lbs should be the maximun people should weigh. I'm a strong guy and 275lbs is pretty hard to even push around let alone pick up a fully dressed person in distress.
