That sucks for providers for sure. I hate hearing it because it can cause issues for clients as well.. as in casting doubt on intentions with a new provider. As such, I have a full profile on my RM account, and always text outside of the platform after initially touching base.
Unfortunately, my job is my biggest issue... I travel all over the country.. but every once in a while, I'm hit by the issues with the aviation system (I fly for a major airline), and as such, sometimes I have to cancel. It's only happened 2 times in quite a few years, but it sucks. I always explain why (and feel like a flake.. I feel horrible for it) and have so far had good responses. As such, I get somewhat gun-shy about setting something up too far in advance when I'm on the road. I guess I'll just deal with it as I can.
When I was new to this, I was VERY nervous about the whole thing. Letting a stranger into my life for a sudden level of intimacy/sex was both exciting and frightening. I still never flaked, though.. just never booked!
Hoping it gets better for all providers!
