on a different note. been there done that. some how getting to class, only to find out instructor themselves maybe late or showing up and only a handful of 20 to 30 folks showed up and being canceled. sometimes not.
but being late *hhmmssss* without notification / communication with instructor and/or employer. no communication = making situation worse. earlier the communication starts the better has been my experience. get the situation figured out and get to class! even if it means freezing the rear off, standing around waiting.
