No. I don't eat ketchup. I'll have it once every year or two. Steak sauce is a never. I've had some things called steak sauce that were dressed up ketchup, and I like them on other things, but only as ketchup. Fries, hotdogs, that's the kind of thing I'd put it on. A1 though? Absolutely never. It smells like something that should be kept in a 50 gallon steel drum and used to take the paint off of large steel structures, like telephone towers or the Golden Gate Bridge. And it tastes worse.
It seems like everyone I know puts A1 on their steak though. A guy at work wanted me to eat some of the steak he brought for lunch. It was smothered in A1 and I had to politely decline. I took a girl out for dinner a few weeks ago, she got a steak and covered it in A1. I don't get it, the stuff is absolutely terrible.
