Smoking in places people eat. I get irrate frankly. The last thing I want to smell or look at is someone lighting up as Im trying to eat. It puts me in an instant foul mood. Thankfully where I live they recently in the past 2-3 months made it illegal.
My unit manager. Shes condesending and unprofessional. I hope to someday meet her in a bar, get horrifically drunk, and instigate a bar fight with her. She would so deserve it.
