Q: Do I need to refrigerate Ketchup?

A: Because of its natural acidity, Heinz® Ketchup is shelf-stable. However, its stability after opening can be affected by storage conditions. We recommend that this product, like any processed food, be refrigerated after opening. Refrigeration will maintain the best product quality after opening.

If Ketchup needs to be in the fridge, then why does every single restaurant I've ever eaten in have it room temp when they bring it to you? I've also worked in restaurants and they don't store it in the fridge either.
