@woodpunk this is going to sound fake but it honestly happened at my brother's practice: a woman came in and asked to file a formal complaint. After some haranguing the receptionist calmed her down, saying she'd get the form but what exactly had gone wrong? "I was really badly treated when I was here for an optician's appointment last week..."

(I'm sure you can guess the next bit...)

I'm sorry ma'am but this is a dentists?

(only about the 3rd weirdest thing that's happened there)
