coffee cup

Here's a fun tip, quite drinking coffee. Wait, that's not the green tip.....

Okay, if you must drink coffee, on any other beverage of your choice, don't go for those cheap throw away cups, get a mug.

I don't even know why this is a tip in all the literature, but since it is, I'll throw it in here. Honestly? Why the crap wouldn't you use a reusable mug, it goes against my logic of thinking. I'm so confused....
