I can't shit when i see other person's in the toilet bowl

I can't for the life of me shit into the toilet bowl when I see unflushed shit of other people still floating in there. It makes me feel awkward and disgusted by the sight of it. I also need to thoroughly watch out for some small chunks of other people's unflushed shit in the toilet bowl. I will be doing the charity to clear these people's mess first before daring to use the toilet.

Whenever I finish doing my business, I would make sure mine is totally wiped from the face of the toilet bowl because the thought of someone else seeing my unflushed shit and getting disgusted by it is utterly embarrassing.
