As it should because your stomach is wise. Ha ha, I still remember when I first went to college and I'd stop over a nearby Mickey D's for breakfast and my stomach would really get pissed off.
I had a taco with egg, mushroom, and maple sausage and half a mocha Starbuck's frappe mixed 1:1 with skim milk. I probably should've worked some spinach into the taco. I find adding greens keep the egg from, er, "reacting". I have to do that with barbacoa because that shit's too damn oily. And we buy it without the fat.
