Let me say this, just because a person has dark skin does not mean they're ONLY black. Please be mindful of what and who you speak of, when speaking Spanish. Know your culture know where you came from. Know this your parents and ancestors are BLACK!
The waiting is a bit much, when the person you have to see is just standing around gossiping.
Have a little more respect for the patients when they are seeing the doctor; walking in without a knock on the door just to say something that could've waited until the persons visit was over is a bit much as well.
