I guess no tea? No cookie? It's rediculous but what I like to know is if you asked the one who told you to do this to show him/herself first. You have no idea whom you are talking and who says you, are you? You can ask anyone to hold that teacup. And what if you are not able to make a selfie? I wonder what will happen if you have 200k in your wallet. Will they ask you as well to serve tea cups? What if you don't have a tea cup?
