How would you approach this? I have a male acquaintance that I work with who pulled some flaky stuff while trying to meet with me for a social event (not related to work) - this person set the time to meet, but showed up two hours late for us to travel together. I did express early-on that I had plans afterward, but that didn't seem to sink in. After a few "warning shots" including a text giving the exact time I was walking out of the door, I ended up leaving, and then got text messages afterward reading, "Hey! Where are you? I just got here!"
My acquaintance is still a pretty likable person, and again someone I have to work with, so I need to resolve this and not have it be awkward. Thoughts?
