The owner notified the cops.
I find it strange that the owner would even have to contact the cops about such a health hazard. If the owner knew of the possible contaminations, why not find out who’s been doing it, or who else was on shift, then get rid of them?
If the owner really made this last quote, then HE is a big part of the problem “I have been made aware for quite some time now that some of my employees have been spitting in officer’s food and now I know why, because you are all bullies.”
