I didn't get a chance to make dinner for my date, so I got her McDonalds
Oops.  That's doesn't have to be a bad thing.  No one can resist fries from McDonalds.  How did she react?
She seem kind of surprised, but she did eat everything. Not a fry survived.
Well, there you go.  She enjoyed it and if she didn't complain or scoff at you, then she sounds like a keeper!
