It is a reality your employees will steal from you at some point, unless you pay them truly astronomical amounts (and even then...) When you have just one, perhaps you will get lucky. With multiple it is a matter of time.
A company I worked at, when we got nicer offices that had actual showers, had someone take a dump in the shower within the first month of moving in. I think we were around 1500 employees at the time. It would never occur to me that this would happen, but now I know to expect anything once you get enough people together.
