Yeah happened to me. I had a low paying job for Seattle and decided to ask for a raise after I fixed a couple of seriously expensive bugs in our S3 management scheme. They told me that I would only get a raise if I had another offer. I said "There doesn't need to be another offer for me to get a raise" and they disagreed. I am now making 57% more at another company which is less fun but definitely more lucrative.
