Missouri lawmakers are trying to block Kansas City's plan to ban single serve alcohol sales as the city prepares for a crucial vote on the measure. The measure, which targets small bottles often sold individually at convenience and liquor stores, would limit sales only in designated zones identified by the city. However, Missouri House Speaker Jon Patterson is attempting to block the proposal by adding an amendment that would prevent Kansas City from moving forward. He argues that the ban could harm small businesses and raise legal concerns about equal protection. However some local store owners have voiced frustration over not being included in the process and warned that the restrictions could significantly impact their revenue.
