How do you even review your local blood bank???
"They are much gentler drawing blood here than the waitress is over at IHOP. She always bruises my arm."
"The donor chairs are much more comfortable than the lobby chairs at Jiffy Lube."
This is such a specialized service provider that it's hard to review it, but it's a good one. They haven't hurt me or done me wrong. So, it's where I repay my debt to society. No, no, not like community service or some court mandated repayment thing... Five years ago I received almost 8 units of blood after a massive surgery, basically keeping me alive, so *this* is how I pay back my debt of gratitude.
(Plus, the chairs here are so much more comfy than the Jiffy Lube lobby chairs.)
