Have any of you that are Instructors for conceal carry ask students to pay in advance for class ? or have them pay afterwards ? The reason I bring it up is after ordering and buying the materials ,then taking time off work because they wanted a private class one won't return calls and another canceled stating he was going to take the "gun show "(what a joke ) cuz it's only 2 hours long (u learn sooo much ) . Am I wrong by being ticked off ? Just wanted to hear some perspectives from other Instructors .
