This type of teacher will do all they can to have physical contact with you. They will call this an "adjustment". If you are averse to being touched, you should probably roll your mat up and leave then and there. You will be able to spot them before class because they will be the ones hugging and rubbing the shoulders of the students as they walk in. Once the class begins, you will be subjected to rubs, caresses and pecks on the cheek.
TIP: Don’t moan.
