Sprint review: unethical behavior

I am the manager at Great Clips, which is located next to one of sprints corporate stores, I am also a customer of sprint. We understand you sell electronics and like to demo them for your customers but, should a young child getting a haircut hear the words "Back that ### up", through the walls. You could choose a more appropriate station to help your demos. As a sprint customer I know that your customers can be in your facility for hours at a time, you are supposed to have a public facility available for them, we do not appreciate having to clean up after your customers. Again your customers are in your stores for a period of time, they should not be blocking our place of business for hours upon end. Extremely fed up
