So I'm at a restaurant and I ordered some French fries and ketchup. Instead of the ketchup being in a brand name bottle it's in a red one. So I put it on my fries and it kinda was more acidic tasting than normal. I'm so panicked. I only ate 4 bites. But does ketchup actually go bad???? Wouldn't it taste really bad instead of extra acidic/sour????? Am I ok???
