Only Daves are Allowed Beyond this Point
This is an oddly specific note for what is probably some sort of workplace refrigerator. But the warning is quite clear. We can imagine that the Dave that wrote this note is the only Dave that works in this place and has most likely had his favorite green tea drink poached on more than one occasion whether intentionally or unintentionally.

This hilarious note is a foolproof way to ensure such a mistake never happens at all. Now everyone that opens the fridge knows who owns the drink and will steer clear, hopefully. And what if another Dave joins the company? He might have to think of another cunny way to pass the message along or settle to share.
