This is the sort of thing that bugs me. Society here is in general a lot more wasteful than they have to be. I was at this, let’s say cafe the other day. (Yes, hiding the name to protect the privacy of the employee of that place and all that jazz). I ordered a medium Dew. She says ok, and fills up a small cup. Then she looks at me and goes, oh, you asked for a medium right? I nod. She just pours out the small and fills another one in a larger cup.
Ah well, you make whatever you want out of this.
