I rarely get a NCNS anymore. Last one was over a year ago in Shreveport and I had become so fed up with them I posted about it. Prior to that one I just shrugged it off and wrote the provider off for any future visits. I did share the experiences with other hobbyists through backchannels. In that one I posted about I promised I would always post about it when it happened.
Yesterday it happened to me again here in Dallas from a provider I have seen many times and does not have a reputation for doing this. Kinda ruined my whole day. But I was mindful of the advice I have read on here about posting about these things too soon because sometimes there is a good reason. Didn't seem like it could be given the circumstances but I decided to wait a few days.
This morning I received the nicest PM explaining the reason and apologizing. She also made a quite generous offer to make it up to me. The reason given was legitimate and I understood completely. I look forward to the make up.
