In my defense, I've never seen a beater being used in real life. I mean, it's a "luxury", at least in my part of the world. Just use spoon for beating eggs, cutting butter and picking noodles - yeah, slightly inconvenient, but you can live with that.
Yesn't? Okay, just a small, single little bit to check the consistency. Honestly no one would want to lick a dosa batter, it's pretty bitter. Maybe guri appa is an exception.
