Washington State has such restrictive laws that it would be nearly impossible to have a strip club that served alcohol. If you did want to have such a thing, the liquor code specifies "Entertainers may only expose their breast and/or buttocks if the performer(s) is...removed at least six feet from the nearest patron." It also says they may not "wear or use any device or covering that is exposed to view which simulates the breast, genitals, anus, pubic hair, or any portion thereof." That means no simulating pubic hair, which means no merkins.
