I would suggest the two on Richmond Avenue, 1/2 a block off of Greenbriar, the two right next to each other. If that isn't old enough for you, try across the street at Emerald Spa. the old ones r there usually during the day, they can stay awwake at night. Also you can try NK Nails on richmond on the other suide of town near Chimney Rock, sometimes they are old, sometimes not.
If you go in and they are not old enough, tell them you were looking for someone older. They know who is at what place and can direct you, if they want to, to an older lady. It is a good question because basically you are saying you look to young, you have no downside asking, not like when I say have anyone younger? that makes for an awkward moment or two.
