nice. well the time I mentioned was hitting with a good friend. I thought it courteous, it didn't occur to me that it was stupid. No I don't warn about serving out wide etc.. but return positioning for an underhand serve is completely different than the positioning for the normal range of serves. I was interested in playing good tennis not going for cheap points. The conditions dictated that I reluctantly serve underhanded so I gave him fair warning, sort of like "here are the terms by we're going to play this service game". Stupid to you I guess, sporting to me. Had it been a real match of any consequence I wouldn't give warning and probably wouldn't serve underhand to begin with.
