Scuzzy
Many customer-mistresses wear quite scuzzy footwear on their commute to and from work - changing into their smart businesslike footwear when they get into the office. however, that doesn't mean they don't require me to spruce up their scuzzy flats to the best of my humble abilities. I do the best I can, though it's well-nigh impossible to remove ingrained streetdirt with just the tongue alone!
My customers' socks can sometimes look a bit scuzzy as well. Then again, I'm one to talk. I'm covered in dirt - the shoe and boot dirt from my customers!
