Blood=Bruise

I have given blood on many occasions. So many in fact I have a blood donor card. Well, I went to donate blood at the Milford blood drive and ended up with a huge bruise. This bruise is the size of a softball. My bicept it really sore also. Why can't I do anything without it turning into something crazy? Can I just get a break? The blood getter guy missed my vein and then chased it and then adjusted the needle on a few occasions. Good thing it is for a good cause or else I might have to pop him in the nose and give him a bruise. JC wasn't too happy about it either.
