Have you ever stood in line at the coffee shop determined to be a good little coffee drinker and order non-fat milk? Then as you're downing your quite rich and creamy coffee, you wonder if you really got non-fat after all?

A Glamour blogger recently wondered if baristas ever mess with your coffee drinks. After all, it can't be easy to remember grande, skinny, mocha and all the other variations that can be ordered. One Glamour reader commented that in her experience, yes, it can happen. Maybe there's a long line and there's already whole milk perfectly steamed or maybe a certain milk must be used up before it goes bad. Whatever the reason, there's certainly a chance of not getting what you ordered and you might not know the difference.

Is coffee confusion a catastrophe? Of course not. Just know that when you stop for a specialty coffee, you're also probably getting some "specialty" calories. When you make it at home, you know for sure what you're getting -- and saving some coin in the process.
