Wavey

I'm in the cafe I work in. A regular customer leaves and waves goodbye to me. I wave back at her. Unfortunately it's a bit of a purposely gay wave. Unfortunate because a new customer standing between us thinks I am waving a greeting at her. She waves back at me. This really isn't how I greet customers. She thinks otherwise because at the completion of her meal, as she leaves, she waves at me. It's quite possible she thinks I am simple in the head. Reluctantly, I smile and wave goodbye to her. The others I work with think this is a cack and now they wave enthusiastically at me at the start and end of each day.
