Our company stocks up cupboards with food for employees to share, bread, butter, milk, jam and loads more. They also have nutella and I just want a teaspoon of it but I don't want anyone to walk in. A teaspoon is only as much as you'd put on 2 slices of toast so I'm not having any more than my fair share, but I don't want toast I only want the chocolate spread, but it just doesn't seem to be an acceptable way to eat shared food so I'm too embarrassed.

I'd use a clean tea spoon and wouldn't put it back in after I had it because I only want a spoonful...
