From CSI (Costco Secret Informant):
Dear "I want one from the bottom" shopper,
I saw you shopping today, digging through my product and throwing empty boxes behind you. I waited to see if maybe you would pick up that box you just put on the floor, of course you did not. You walked away as if the box was already there and you glance at me insulted because you had to walk around it.
However, I SAW YOU put it there. Yes, I see everything you do. I know what you are doing even when I am not looking at you. How you ask? Because there are so many of you and you are all the same!
I have a question for you. Why must you get one from the bottom?
I know you are assuming its "fresher" or "newer". Most of the time they are not though. They are either all the same date or occasionally the older ones may end up on the bottom. Older on the bottom you gasp! Yes, because random people sometimes get their hands into the department and stock it wrong. 
Sometimes I want to save you the embarrassment of lifting boxes and looking like a fool (oh yes you do look like a fool!) but mostly stop you from the mess you are creating! So I tell you that they are all the same (why would I lie?) and there you go digging towards the bottom still. Do you realize how stupid you just made yourself look?! Do you realize that you are the butt of the jokes of every employee in the store?!
The other day I encountered one of your "buddies" they went straight for the product without looking at any of it (and they never do look).
I proceeded with my normal, "they are all the same" line and I actually got a response!
"*insert nasty tone* The ones on the bottom look better!" 
Now, I might have believed them if I had not just personally stocked that product and knew they were all the same date, came at the same time and even from the same place! I might have believed them if they even looked at the product on top. However, they did not even look at the product they grabbed from the bottom!!!!! Idiots!
I just really wanted to let you know how stupid you look to the world, the employees and the few "normal" shoppers.
I also wanted you to know how horrible you make my day and how much you ruin my mood. Do you enjoy making life hard for other people? Does it make you happy?
You know I would not have an issue with you reaching into the bottom if you had the common courtesy to not make a mess. I watch you move boxes onto the floor and on top of other product (you are crushing and ruining product btw!) and then you walk away! Why?!
No, it is not my job to clean up after you. It is my job to have product out for you to buy. Which you make impossible when I have to follow you around like the small child you are and clean up your mess. 
Then you have the nerve to come to me and demand to know why something isn't out for sale!
I have time lines to keep and managers to make happy; you come in and make it all last longer and get me in trouble for not having everything finished because I had to fix the mess you created!
Do you realize the hassle you are and the problems you create?! I hope that stuff you got from the bottom rots quickly and I hope you got the oldest product we had. Why?
Because you don't deserve good things for the trouble you cause. I hope you have a horrible day, just like the one you create for me.
