ND redsun: Did you contact her ahead of time? Like a day or several hours in advance to let her know you were coming to town and wanted an appointment? If so, your point is well taken.
If not, and was truly only a half hour-an hour prior to like Carly states, that's kinda considered last minute, so you can't hardly knock her for that. It's always nice when last minute works out for us horny dogs, but if it doesn't, we can't really complain. And maybe an apology is in order?
Nice avatar btw Carly
