Totally agree, make the effort. You are your own and best advertising and you have the freedom to do whatever you like to show your nails off. I also agree to keep it simple if thats your thing and a fancy pony tail thingy is always good. Always try to make a good impression. Also once your showered and made up, smelling sweet doesnt it make you feel better about yourself too? I am not saying you have to be cat walk glam just clean, tidy and well pressented.
