A recent study has shown that consumers have sometimes been short changed when shopping in supermarkets and markets, while businesses were found to have underpriced items in other instances.However, Minister of Energy and Business Development, Kerrie Symmonds does not believe situations in which customers received less than they paid for were generally intentional.He spoke about the study conducted by the Barbados National Standards Institute (BNSI), which highlighted several instances of consumers either overpaying or underpaying for goods at several businesses, supermarkets and markets across the island, as he led off debate in the House of Assembly on the Barbados Metrology Bill, 2022 on Tuesday.He said the BNSI checked several products including sugar, bottled water, weighed food, potatoes, chicken and fish.
