I don't think they'll do it because there is lettuces, carrots, mushrooms and other vegetables in it and sometimes i saw flies inside. 
As you can see on the video there is a opening big enough for some insects. And the stickers are just on plastic wrap food and eggs nothing serious.

but it's true i should find the owner and orange pill him about bitcoin & business. 

I have also leave a couple of stickers time to time on a table there 

 That's the 'if they are half competent' part.
I don't think they are. 🤣
