Many cities have been adding on soda taxes. In order to offset these taxes you can try to reduce the amount of soda you spill and reconsider your refill policy. Don’t let customers refill their own drinks, and if you do, try moving the drink station to a less convenient location. You can also consider using smaller cup sizes. This has been a long standing practice in grocery stores for years! Lastly, make sure you stay transparent and also have a smart pricing strategy.
