Q1. Colin knocks on a front door of a house and says to Kevin (who answers the door) that he has noticed that the garden of the house has a lot of uncleared leaves on it. Colin offers to clear the leaves using his leaf-blower and garden vacuum, to which Kevin agrees. When the task is completed, Colin asks for $50 payment. Kevin refuses to pay Colin as there was no mention of any payment when the original agreement was made. Discuss the elements that may determine whether or not there was a legally binding agreement between Colin & Kevin and if Colin should be paid or not
