Best/fun case: when I was contracting some years ago, if you had your laptop unlock someone would send an email to the project team "coffees are on me! let's pick them up after lunch", and they would pay (but everyone's daily rate was multiple hundreds of GBP per day, and that would pass as 'expense' so the total 40-50 pounds didn't hurt much). Worse case: (same company) someone send an email to all infra team (including the VP) that "I'm stupid and I don't lock my laptop". That guy (the 'funny' one) was kicked out of the project/contract/building within the hour. My friendly advice, lock it for them, when you see them again take them on the side and tel then "hey dude, lock that damn thing" and move on with your life.
