A salesman who got slapped by a lady customer when his right eye winked without his control

1. 45-year old man presented with involuntary #winking of right #eye of 6 months duration. It occurred several times in a day and he could not control them. He had no other symptoms.
2. He was a salesman in a cosmetics shop and most of the customers were women.
It was a usual day for him at work when his right eye winked at a lady customer (while talking about a product). She misunderstood it and slapped him. All his explanation could not pacify her.
3. With help from his boss and lengthy discussion with the woman's family, the matter was amicably resolved.

However, his job was at stake and he decided to seek a Neurologist's opinion.
