When my ex-wife and I worked for National School Assemblies, one of the things we had to do was to collect the check PRIOR to the performance. (In most schools.)This was company policy, and if an expected check had not been cut, we simply called the National main office and let the "boss" handle it with the Principal. But before that, we had to at least try to get the check. When we arrived we would usually speak briefly to the Principal. We'd go over the arrangements and before we went to set up, if he had not volunteered to give us the check, my ex would say: "Can you tell us how to get to the bank when we finish your show?"
Generally the Principal would ask which bank she was looking for, and she would say: "Why the bank your check is written on, of course, we need to cash it for our road expenses!" Of course, she was a very foxy lady, and she said it with a really big smile... but the first time she said it, I almost broke out laughing. It did, however, work damn near every time.
I was with Stan Kramien many times when he was settling up with the sponsor on the shows proceeds for one of his full evening shows. He always arranged to meet the club treasurer at the bank at noon of the show day. They'd go over the paperwork, and calculate how much was owed to Stan, and he'd get the check. He would also have the treasurer stick around while he cashed it in case there were difficulties. Even though the contract stated that the show was to be paid the day of the show, there were occasionally difficulties. Two signatures might be required and the other signatory was out of town... etc. More than once I saw Stan look the sponsor right in the eye and say: "How well do you do magic, John?" Sometimes they didn't get it and he'll tell them right out: "No check, no show." There would be some awkward moments, but when they realized that there were going to be several hundred people arriving to see the "Rotary Club" magic show, they ALWAYS managed to work it out. Stan did not relent.
