With year end reviews coming up, I'm wondering if I can tell my boss that I denied an offer to leave my current job. I denied an opportunity to get a ~40% raise, so I feel like I could potentially get my current employer to pay me more or at least get brownie points for loyalty.
My worry is that they would be unhappy that I interviewed somewhere else in the first place. Any advice is much appreciated.
Edit: Since the only responses I've received are people telling me I'm dumb for not taking the offer I'd like to expand on the context. First of all, I'm currently in my first job out of college and I've only been here for 7 months. If I jump ship this early I would be locked into my next job for at least 2 years and I plan on moving cities within the next year (likely transferring internally). Also, being so early on in my career I'm currently much more focused on the type of experience I'm getting as apposed to how much money I'm making. The offer I received would've been a bump in pay but its also a specialized role in a niche industry I'm not interested in long term.
