I'm NOT ready for my closeup

I used to do my own eyebrow waxing, but about a year ago.. Common sense finally fell on me and I realized this is a pretty dangerous thing to do by yourself, especially if your fond of your vision.
I began patronizing a sweet girl who at first, of course, needed me to explain to her, what I preferred, but after a few waxing's.. She just remembered how I liked my eyebrows and did them perfectly.
I have weird eyebrows, because back in the 80's I saw sparse eyebrows in some magazine, LOVEd the look and decided to pluck the heck out of mine, so they didn't look so dense. Well, I created a bald spot that NEVER grew back! I've been warning women ever since..."BE careful about how thin you make your eyebrows, They eventually STOP growing back". After years of styling women's hair, I can't even tell you HOW many women have told me they have had horrendous experiences with their eyebrows Never growing back.
So, to camouflage the bald space I keep my eyebrows thicker than I would like so the lower hairs make a border and the bald spot is above that and it doesn't look so bad. Does that make sense?
I had explained all this to Kim on my first few visits. I told her I didn't like eyebrow pencil and my solution prevents me from needing it. Today, I was Kims first appointment. After a few minutes of my waxing I hear her Mumble a foreign word. (Later, I would realize It must have been the Korean translation of F@*K ) I said " Is everything all right?" NO answer. A minute later she sticks her head out of the waxing room and Starts speaking Korean to the owner of the salon. I have my eyes safely closed and I'm feeling more relaxed than usual. Immediately the owner is looking over me, I open my eyes " is everything Okay?" With that Sweet Kim just breaks down crying!! I'm talking Hysterically crying. The owner explains to me, "Kim made a little mistake." I felt so sorry for Kim, it didn't occur to me to ask for the mirror! I sat up and tried hugging her, I said "Kim! It's okay, don't worry, are you okay?" The Girl was inconsolable! She wouldn't look at me! She just had her face in her hands and was SOBBING!! The owner just looked at her and didn't try to calm her down at all.Instead, She handed me a mirror. Apparently, Kim took off that lower border that I was using to shadow my bald spot. OH WOw! It IS bad. Inside, I thought "oh shit! How do I fix this?" but outwardly, I said 'Oh it's not so bad, Don't worry Kim, I'm not so fussy, I will just use pencil." She finally calmed down! Her crying really softened the blow of my brow! If she would have been nonchalant about it, I may have gotten upset.
I can't believe how calmly i reacted. ESPECIALLY, when the owner CHARGED me for my bald eyebrow!! Normally, I would have said SOMETHING for an injustice like this, but I was still feeling, fragile Kim, would fall apart at anything relating to her 'accident'. I sucked it up and paid the 8 bucks!AND of course tipped Kim as well! Let me tell you though, I am seriously thinking of never returning. NOT because of Kim, but I think the owner Handled it so poorly, especially that I am a regular customer. What do you think?
