Greetings.
It's certainly not our place to tell you how to handle a staffing issue, but we would certainly recommend having a camera system in your restaurant. Not only can it help in a situation like the one you are facing in managing employee theft, it can help protect your establishment against false liability claims and other damages and assist in numerous other issues when dealing with both employee and other issues with the general public. We would love to assist in quoting a system for your sister's restaurant. If you are interested please have someone contact us at (561) 288-5258 ext. 2 and a sales agent can help design an appropriate system for your needs.
Sincerely,
Aldino Frassinelli
