I have a side rant to this. Often I have worked as a salaried employee or an hourly employee among salaried employees. The half hour or hour-long lunch break seems to get stretched by some, rather routinely, to 90 minutes or two hours leaving others to cover the time. It seems there are certain people who just do this as a matter of routine and it doesn't seem to matter to those in charge.
