Obviously, you aren't looking in the right spots or times. Lots of strip casinos have $5 BJ in the early mornings, and some will grandfather you in when they raise minimums. Otherwise- Sahara, Circus Circus, Slots of Fun, Riveria, Casino Royale , OSheas, Westin, Ellis Island, Hooters, Trop, and Excaliber on or near the strip offer them most weekdays.
