11. Dentist Appointment
Possible variation – physician appointment
Most of the people really hate going to the dentist. If your boss is one of them, then they can relate to your pain, and give you a day off. If the boss asks you why didn’t you schedule your dentist appointment during non-working hours, you can say something like this was the only available time my dentist had, before taking a holiday, and that you are having a toothache for a while and can’t miss it. In any case, you should at least get half a day free.
