Returned gear late. Normally I'm pretty flexible about returns but I voiced my need for a punctual and timely return, because I was hired on a gig the next day. I was promised the gear would be returned that night. I woke up to find the gear had not been returned as promised. This created a very stressful situation for me as a sound mixer showing up on set without the necessary gear needed to perform my duties. I won't be renting my gear to this individual in the future.
