I suspect dipping steak in butter is a pretty unusual, and dare I say eccentric, culinary practice. I don't ever recall ever having seen anyone else do it or anyone who just wasn't stunned when they see me engage in it.

A little OT - when I was a kid, I kept complaining that my steak didn't have enough flavor or fat; my grandma got so tired of my whining, she just placed a cup of melted butter, told me to dip my steak in it and be quiet (she actually used "shut-up, if I recall).
