Zolol [24]

I personally would choose Ice-cream taster, but judging from context you wrote in this specific question. This isnt something with a wrong answer but rather a personal question. I think you should be the one answering this because with the context that I see on what you wrote. This isnt something like an equation, if Im wrong, I mustve missed out on some context or Im not getting something right. Therefore, you should choose what you like on this since it looks like a personal question.
