This may be a bit off this topic, but what about providers who message you looking for gifts (such as dinner, but not with me) after you have set a meeting date.
Am I overreacting to this being a hard pass (this guy is rather famous, not that it should change etiquette in my view)? After the second time this was requested, I let him know what I thought (in as nice a way as I could), so I probably pissed him off and should just cancel the meet. The meet was setup for in October.
