I prefer the impromptu meetings, but only if they message me and ask. There's been a few times where MFs will just call me out of the blue and expect my participation. I don't mind helping people - shyt I'd even go so far as to say I enjoy helping people - but you gotta ask for it first. What I hate is when people schedule meetings with like 15 people on the call, but there are only like 3 interested parties. My PM does that, just loves to schedule meetings for the sake of having them.
I feel you, but yesterday the timing was off. I had like three meetings, half to one hour between one another and someone taking that time in between to show something. It was like a 5 hour string of meetings and I was just exhausted at the end of the day.
