I heard about this off of the internet a few days ago. This idea from Bloomberg is not gonna fly to me. You can't tell a restaurant which drinks thye should serve to their patrons! But if an antismoker thinks banning large pop drinks in a restaurant is dumb, then you're slowly starting to see why certain smoking bans are dumb too.
This idea is all about dictating how businesses should run. Just like with smoking bans controlling businesses too.
