Monkeys in the sugar bowl?

[A notice posted on the staff e-mail board regarding the coffee supplies in the teacher's lounge]

Dear Colleagues,

We have lost a second sugar container. It looks like the container was left open on the counter and maybe monkeys came in and took it as the lid is still on the counter with sugar all over the counter. Please be responsible and close the container after use and put it back into the cupboard. Also, please help by keeping the outside door closed as there are many monkeys around the tea garden area.
