Once, i had an entire day double booked (plus multiple hours before and after my working hours) and one hour in particular was quadruple booked. People were shouting at me all day about how I wasn't showing up to their meetings, but like... you could see my calendar when you put those appointments on there. That's kind of on you.

I got a talking to from my boss but they didn't reprimand me or anything, it was just "managing these kinds of things is an important part of the job". Eh. They did not pay me enough.
