Plus, you get goodies!!! One time, I got several pints of ice cream (Blue Bell). I've gotten tshirts. Some people in the thread have gotten even homemade stuff.
And I feel like some kind of celebrity!

Yesterday, one of the ladies kept wanting to know what she could bring me while I was giving. Did I want something to drink? Something to eat? How's the show they have on the tv right now? Did I like it or did I want it changed?
They know me there (I've been in enough trying to give even when I wasn't able to). So they know me by name and are super sweet.
A suggestion - ask for the most experienced tech they have. Even if you have to wait for them, they may have some tricks that will help a new donor have a great experience. I did that. And my person was excellent. Really made it fun. He had a great sense of humor, put me at ease, and didn't hurt me at all.
