I dont know if you are trying to avoid the whole chain-butcher situation but Harris Teeter will do a thick cut if you ask, Whole Foods butcher (right accross the street from El Chapparal) will do the same plus if you are looking to splurge there dry-aged ribeye is delicious. I am a huge fan of El Chapparal the meat and produce is cheap but I fear you get what you pay for.
Try the Lebanese Butcher in Falls Church -- this place is right off Washington Street/Lee Hwy/Rt. 29 just south of Rt. 7/Broad Street. It is a great butcher with all kinds of meats and it also has a restaurant right next door with great Lebanese food. They will cut your steaks however you want them, and while they are doing that go next door and grab a meal or carryout.
If you do a google on Lebanese Butcher you can get the exact address.
