It's just a septum ring

So, I work on Mt. Lemon (at the Cookie Cabin). Today, one of the first customers who came in for the day were an elderly couple. They walked in smiling and not taking their eyes off one another. I smiled at them as they approached the front counter and gingerly asked what they would like to eat. The man turned his attention toward me and immediately ceased in his laughter and grinning. He squinted his eyes at me, bringing his face closer to mine. Scrunching his nose and bringing his upper lip over his teeth, I could tell he was making this face due to the piercing hanging out of each nostril on my face. He let out this incredibly obnoxious laugh, and turned back to my raised eyebrow expression, saying in-between gasps, "I'm sorry! I thought boogers were hanging out of your nose!" Now, it's okay when my family members say that to me, because they are my family, and they know it's an actual piercing, but they just enjoy teasing me. This was a complete stranger who felt it was somehow appropriate to make a comment and proceed to laugh in hysterics at someone, who is about to serve him a meal. I've never had a person mock me so openly before, and I had the desire to rant about it. I then proceeded to stare at him with a blank expression, saying, "No sir, it's not a pair of boogers. It's a metallic piercing that runs through a hole in the septum of my nose." Now, I may have just been sensitive about this, but I placed myself in the opposite role: seeing something completely foreign to me on someone's immediate facial extremities. Pondering on this, I do not believe I would view it socially acceptable to laugh at the person, or openly voice what my initial thoughts were, had they been negative. Perhaps this is just my sensitivity as a female being expressed through this viewpoint, but I thought I would share and get any input through you guys. See you all on Wednesday.
