850.06 ISSUANCE OF LICENSE.
   Upon receipt of the application for the license required by Section 850.02, together with the appropriate fee required by Section 850.04, the City Clerk shall make such investigation as he or she deems necessary for the protection of the public good. If, as a result of such investigation, the applicant's character and business reputation are found to be unsatisfactory, the application shall be denied. If, as a result of the investigation, the character and business reputation of the applicant appear to be satisfactory, the Clerk shall issue the license. If the applicant's character and business reputation appear to be unsatisfactory, the Clerk shall refund the license fee, less five dollars ($5.00), which shall cover the cost of the application and investigation.
   No license shall be issued to a person under eighteen years of age, except that this limitation shall not apply to street trades as the term is defined in Act 157 of the Public Acts of 1947, as amended (M.S.A. 17.728, Sec. 28, as amended).
   No applicant to whom such license has been refused or who has had such a license revoked shall make another application for such a license for at least six months after the last previous rejection or revocation, unless he or she can show, to the satisfaction of the Clerk, that the reason for such rejection or revocation no longer exists.
