There remains the question as to whether such an enterprise is a school within the meaning of the act. In Barwinski v. Liquor Control Commission, 365 Mich. 17, where a 20 x 80 foot music store contained four windowless teaching rooms varying from 6 x 8 feet to 6 x 12 feet in which not more than four students could be given individual lessons at one time, it was held such an institution was not a school within the meaning of the liquor control law. Defendants contend, since Murray's Beauty Academy is conducted in a building which is also 20 x 80 feet, serving 70 students instead of 113 as in Barwinski, that said case is controlling.
