I have always disliked getting coffee in a styrofoam cup that is way too hot to drink. I always drink my coffee black, so nothing is added to cool it down. The styrofoam cups at fast food places keep the coffee way too hot, much longer than a ceramic coffee cup would have. If the coffee at an ordinary restaurant is too hot, it will quickly cool off somewhat in the ceramic cup and saucer they use.
I do not like having to sit around, for a few minutes, waiting for the coffee to cool down before I can drink it. After several minutes, I usually get impatient and start cautiously trying to sip the still way too hot coffee. The next day, I have usually discovered that my tongue was sore from having been burned by the super hot coffee. After a couple of days, the soreness of portions of my tongue and roof of my mouth, goes away.
Usually, the way too hot coffee from fast food places smells disgusting. Instead of having that wonderful rich coffee aroma, it usually has that strong disgusting overcooked, burnt smell, typical of coffee made several hours ago, but constantly kept hot for several hours. When I finally get around to cautiously taking my first sip, I usually discover that it tastes even worse than it smells, so I throw it away. People who use cream or sugar, might have possibly have been able to make it taste minimally acceptable.
If fast food place can not provide fresh good smelling and good tasting coffee, I wish they would just not even offer it on the menu.
