This is latest in tossing the coin more than one time - a ceremony that took more than 40" I read the law book and there is "a coin toss shall be conducted ..." Now compare that tossing ceremony with this - a coin was tossed, however the process was not complete (it was not caught), another coin was tossed. No fuss, no scenes, all done and dusted in about 16": An excellent demonstration of teamwork and preparedness. Good practice model in setting the tone right at the outset.
Great videos! And kudos to the service judge for the prompt collection. It is, however, not fair to compare the times in doubles and singles. In doubles, you have to ask two more questions, and confirm the answer. I note that in the first video, the umpire asks the receiving side first who is to receive. I was taught to always ask the serving side first. Is there an official protocol for that? I can find no mention of it in either ITTO or the umpire training manual.
