When you schedule for an H, 90, 120 +, it's in bad form to show up for the appointment and tell your provider then that you'll be cutting your time - and donation - short.
If you're not sure you want more than a HH because she's new or because you may have a RW commitment you have to attend to, bring it up while you're scheduling. I'm pretty sure most of us will be cool and work with you or tell you gently that we need full commitment/full donation.
I'm not talking about a new guy showing up and changing his mind, I'm talking about an overall trend I'm noticing with new guys AND regulars. I know personally that if you respect me and my time enough to tell me you *may* only be able to do a HH, I'm A-OK with it and I can note my donation record books accordingly.
So, while y'all complain about NCNS-ers and providers not replying in a timely manner, I thought I'd throw this one in here. Friendly-like
EFN, OUT
