There are a number of routine tasks that can make people fell nervous - from calling to make a doctor's appointment to getting your eyes tested.
Another thing that may fall under this category is dentist check-ups, as many people may find having someone prodding about in their mouth quite uncomfortable.
As such, some people might end up acting rather awkwardly or out of the ordinary when they attend their appointments and it seems one dentist has seen his fair share of unexpected behaviour at his clinic.
Dr Sahil Patel, a Cosmetic Dentist and the Founder of Marylebone Smile Clinic, has recently shared some of the most unusual things that have ever happened during appointments with The Mirror.
He claims one of the most memorable incidents occurred when a patient took an instrument off him during the appointment and proceeded to demonstrate "how it should be done" to the expert.
Unsurprisingly, it didn't go down too well.
Dr Patel says he has also seen patients become so nervous about their appointment that they sweat so much they end up slipping off the chair.
But the most common of all is simply that many patients fall asleep during their appointments and procedures.
This comes after the cosmetic dentist shared some of the 'worst' things people have ever said to him during an appointment.
He told how the worst offender is "I don't like dentists" and explained: "This is possibly the most common first interaction with a new client, it does not start you off on the best foot since you have just met your new dentist.
"It can be hard to believe dentists are human just like everyone else, and aside from us already being aware that people dislike going to the dentist, I would encourage people to re-consider why they have gone to the dentist in the first place."
Another thing to avoid is telling your dentist you have a "high pain threshold" or that you have "shooting pains".
"This is a classical concern health care professionals receive when consulting with patients. Both assertions refer to pain, which is relative and very personalised and can be modified by the state of mind, lived experiences. memories and counter sense effects," explains Dr Patel.
