I was just referred by the Portage Urgent care to have tests done for a possible embolism. The girl at the counter appeared very rude. Did not even make eye contact. I felt like I was interrupting her day with my issue. It's embarrassing enough to stand in front of everyone in the place and explain what I have for issues and feel like you are bothering someone. I guess my problem isn't that bad. I apologized and left without checking in.
