VBC, I totally understand. I am the only gringa in the practice I go to, and I find that Latin Americans and Europeans have a different need for personal space than I do. The studio is pretty huge, but without fail, the person who puts her (or very occasionally, his) mat next to mine is no more than a foot away. We do stagger them so the fronts are not all at the same spot or we'd be hitting each other constantly, but it still bugs me. I always get there early so I can get the end of the row, so at least I have someone only on one side. But because of how people place their mats, even if there is only a small group of us in the practice (3-5 plus the instructor), we're all clumped up together. It's so strange and one of the only things I don't like about the place I go. Worst part is when we are doing lying twists at the end. I don't like other people's sweaty arms or especially feet on my mat, and it's almost impossible to avoid with the way the mats are spaced. I make very sure I move far to the one side of my mat so I won't infringe on someone else's mat, but others aren't always so conscientious.
RnR, that's a real shame. Our instructor is constantly checking on student's form and assisting, and he does a good long warm-up. The only thing he doesn't do that the instructor in Belize I used to go to did, is ask at the beginning of the class if anyone has any injuries. I have had so many small injuries I always try to mention whatever it is to him before class so he won't wonder if I'm not doing something I usually do, or only doing it on one side. Sounds like you need to find another studio or time to go so that you get a different instructor. Sorry!
