Please don't patronize this business. In addition to being rude and unconcerned with time, they endanger the welfare of children.
I was in this nail salon today, December 26th 2015. There was two minors, ages approximately ten years and 18 months, that appeared to be children of the employees. They were both exposed to chemical fumes related to polishes and chemicals used for nail care. They also had access to all of these chemicals, plus the instruments used for nail care, with little supervision. Since they seemed very familiar with the business, I would suspect they spend a significant amount of time there. Consequently, I am concerned for the welfare of these children and the long-term effects of their frequent exposure to chemical fumes.
