Absolutely! My parents would have beaten my ass if I had backed out of a deal. We had money,( and yes, much more than 250,000) that was never an issue. I was raised to keep your world and never break deals. Obviously kids these days don't follow that, but it's just as much the parents fault for letting them act like idiots. Not all are like that, but you get the picture.
Obviously not high 7 figure's, but I've definitely turned down 60-80k raises for another company, simply because I was happy where I was. There's ZERO loyalty these days.
