Since I started our week late, I'll close this on the fifth day instead of seventh to allow the next person to post.
This was harder than I thought it would be to choose! Everyone's captions were so good and fit perfectly.
Because of the "I'm on duty" and "I know where you sleep" angle which conveyed the possible implied threat pretty well, I'm going to name @TeresaM this contest's winner.
Thanks everyone! And congratst to TeresaM
