It takes time to find a suitable replacement, if one can be found at all.  In the latter case, leaving a client without a scheduled model makes AOM appear unprofessional and tarnishes our reputation.  It may inhibit a regular client from further utilizing our services.

If this situation occurs, depending on the circumstance you may or may not be offered the opportunity to replace your deposit and continue booking through AOM.

A late time of over twenty minutes cannot usually be made up by taking time out of your scheduled paid breaks and disrupts class plans, thus making it comparable to a no-show.  

With art modeling the booking start time is the time that the model is expected to be on stage, ready to unrobe and begin posing.  It takes AT LEAST 5 min to enter the room, meet the instructor/facilitator, find out their posing game plan, set up your dais, and change into your robe & feet coverings.  Arriving late is unprofessional and it disrupts instruction.  It makes both model & AOM look bad to the artists/students, the instructor/facilitator and to the business who booked through us.
