Just lost an offer too because I challenged the pay rate. But... it was also going to be going back to a place I worked at a few years back. I left on good terms and was open to rehire, but yeah. The offer was higher than what I made there back then, but lower than what I was just making at my last job. Sounded like it was in the bag though... but I want change and new experiences.
Ugh, hope something works out soon.
