+# Workplace Laptop Security
+
+## Context
+
+When people leave their laptop open, unlocked and unattended, this could be a big security breach. Especially when you
+have SSO on for multiple services.
+
+## Decision
+
+Whenever a colleague will find your laptop open, unlocked, and unattended, they will message in the `random` Mattermost
+channel of the Rijks AI Validation team to bring a small treat, e.g. cookies or cake to the office the next thursday
+as a way of compensation.
+
+## Risks
+
+- We could have a big security breach if people leave their laptops unlocked and unattended.
+- People could become less healthy by eating many cookies.
+- People could become less trusting of other colleagues if they would be punished by bringing cookies to the office.
+
+## Assumptions
+
+- Everybody is in the RAV team in Mattermost
+- "Next Thursday" is assumed to be the office-day where most people are in the office of choice
+- This won't be abused by colleagues wanting to have free treats
