I once quietly waited over 25mins for my meal while my girlfriend-now-wife finished her dish. When they dropped off our check unrequested (with me still not receiving my meal and with my order on the bill mind you!) I flipped out on the waitress.

Granted, I was just being @ss because I really should have spoke up earlier but I wanted prove a point to my girlfriend who recommended this restaurant which I didn't want to go to. [Yes, she still eventually agreed to marry me. ]
