Yes, this does go both ways. I am always surprised when guys say that cancellations are no big deal as it is part of doing business and part of the Hobby.
I also find that many of the ladies don't seem to appreciate what the guys have to do to get to an appt. That is especially true with guys who are married and have demanding jobs. A guy has to create a reasonable alibi for work and home, set aside time from work, sneak around with the whole communication part of it etc. and it may be his one chance this week or this month to have all the variables come together. Then when the lady cancels, or almost as bad, wants to change the time on short notice , it becomes very irritating. If my whole setup is done and I have a noon date planned, I can't suddenly change it to 2 pm. I think many of the ladies , especially the less mature ones, lead a fly by the seat of the pants life and don't get that in the real world, we have schedules.
Last month I had an overnight set up that required a lot of planning and changes to my routine -- from working an extra 2 hours each night early in the week to create the time, to missing a family event, to changing my personal trainer appt. only to have the lady NS/NC me. Then she ignored texts and emails until I saw her posting on ECCIE the next morning and texted her at that time asking if she was ever going to respond and she acted like it was no big deal. Well, yeah, it was a big deal to me.
I imagine the frustration is just as great from the lady when a guy cancels out , and maybe even more so as she is losing the income that she was counting on, which can be substantial with an overnight.
