Sauces on foods. No, hear me out! Since I was young any kind of sauce on my food really bothers me. I just can't enjoy it and usually don't eat at all or pick around it if I can't get it removed.

Nearly every menu item and nearly every cuisine includes a sauce, and it's often prepared with the sauce in an unremovable state.

Fortunately it's easier these days than when I was young to order it on the side, so I can just not eat it. But it's a mild inconvenience that I'd never wish on anyone (except my enemies).
