<human>: Provide a brief overview of the text.

TIFU real bad. First I have to tell you that I am from Austria, so please forgive me possible typos and grammar mistakes. Second, I live in a very small town (really teeny-weeny) so when I do the groceries I go to the same teeny-weeny store everytime, because I bet you can imagine why- we only have that one.
So long story short- I can never show my face there again.
This is how my story starts: it really was (unlike most of the other stories) today, when I decided to treat my two nasty pimples (one on my forehead, the other one on my chin) like I treat them always when they don't want to go away. I put some toothpaste on them fuckers! 
I did that around 3pm. So when it was like 5pm I kissed my boyfriend goodbye and went to the store. There I bought everything I needed and went to pay. Since I know the cashier I chatted a little bit. You know just how everything's going. Everything was like usual, nothing special.
So then I said thank you and goodbye like the nice girl I am and went home. You have to know I'm very neat and tidy so first thing I got home I went to wash my hands. 
And as I looked into the mirror I nearly fainted. I had strange white spots all over my face. In that moment I realized that I hadn't washed off the toothpaste before going out of the house. I looked like I had the plaque or some sort of scabies. And then it came to my mind that I talked to the cashier for almost 5 minutes. I really don't want to know what she must have thought of me.
And the very best of it: not even my bf told me how I look when he kissed me goodbye. Afterwards he claimed he didn't see it either.
So the conclusion is I feel so embarrassed that from now on I'm going to send my bf to go buy the groceries, I'm not going there again.
