Reminds me of a million years ago (circa 1990) when my hubby and I were shopping for our first computer. Mind you they weren't as common as they are today We went to a computer store (since defunct I'm sure) and asked the sales person some basic questions...Like how much memory he thought we needed. RAM etc. After a few short questions he said to us "It's not my job to teach you about computers. Come back when you know what you want!" I was dumbfounded as well! It wasn't like we'd been there and hour and couldn't decide!
There's those kind of people in all walks of life. The "you should be so lucky to talk to me" sort. Forget them, thank your stars you didn't get involve with them, and hope you find a better person next time! Good luck with your sick kitty.
