Recycling Bin - Organics Only

I have noticed people put the coffee cups in the organics only bin. There are drawings on the bin depicting food, but they are very small, the photo of the girls drinking coffee is more noticeable, so I suppose most people think the cups should be put in the 'Organics Only' bin. 

I let the administration of the mall know about this and they responded very quickly:

Thank you for letting us know.  Our operations group will look into this.
