I regularly use the butcher and the greengrocer because I always get a better deal and better quality than offered by supermarket chains. It's really important to keep small shops like these in business. Once they're gone, they never come back.
Any business using outside space will be charged a fee (for instance florists and cafes). Small businesses, particularly retail, are struggling in the current climate with business rates, rents, lack of demand and difficulties in accessing finance. This new levy, which could be an extra £500-£1,000 per year, is ill-advised and needs to be removed.
