Where plaintiff was to receive commissions for the sale of defendant's property, and an advancement of $20 per week, to be credited on any commissions that he might earn, the only compensation to which he was entitled for showing purchaser over the premises, the sale being subsequently made by defendant's manager, was the advances to which plaintiff was entitled regardless of whether he made the sale. Handy v. Pan Cortlandt Realty Co., 140 N. Y. Sup. 1081, 156 App. Div. 110.
