7-Eleven

I — It’s quite convenient to have a 7-​Eleven within walking distance of my house.
II — The staff is always friendly.
III — The prices, well… today, I was able to get (2) 20 fl oz ginger ales for 2/​$ 2.50 (must purchase 2!)…which is 2 quarters cheaper than Walgreens, where they’re usually 2/​$ 3
IV — TWO: D

Hey guys! You know, coffee is one of the greatest breakthroughs of the modern world. It tastes good, keeps you warm in the winter and gives you a nice head start before a day at work.
That being said, coffee must be made with care. Not like carrying a baby down the stairs or trying to light your farts on fire kind of care; just a reasonable amount of heedfulness. Unfortunately, nobody at this store seems to do it.
Here’s what I mean: coffee has to be served hot. Yeah, I know that’s obvious, but due to the second law of thermodynamics it doesn’t stay hot indefinitely even in those insulated containers. However, the funny thing about coffee is that when it gets cold, it also loses flavor. This once robust and flavorful drink becomes a dry and bland receptacle of glorified mud and will not return to its original saporous state regardless of the use of microwaves or even voodoo magic. Ergo, the coffee must be disposed of.
Your solution to the cold and disgusting coffee is not to dump it out, but to just pour a fresh pot of coffee on top of it. You might be thinking, «Yeah, so? It’s the same drink mixed together. I don’t see a problem.» Well, as a person who drinks his coffee black, here’s what’s wrong:
If you have a fresh pot of coffee and you put, say, a cup of cream in it, what will you get?
Creamy coffee.
If you have a fresh pot of coffee and you put a couple spoon fulls of sugar in it, what will you get?
Sweetened coffee.
Now, if you have a fresh pot of coffee and you pour in the lukewarm, burnt and flavorless remains of a previous pot of coffee in it, what will you get?
That’s right: shit coffee.
Please fix this problem.
