I answered, "yes, you're welcome" and it was accepted, but another suggestion was "yes, please." These seem rather different, how is this phrase commonly used? Thank you!
depends on what you meant to say. If someone asks whether you want more salad you would answer "Так, будь ласка". I can't actually imagine a situation in which Tak, bud' laska could be translated as Yes, you're welcome. That would be Tak, proshu.
