There are a few things that I don't understand here.
1/ OP is ready to put CC details on internet (tickets bought online, right ?), but is afraid to give them by telephone ?!? Is he aware of all those CC databases hacked around the world ?
2/ As OP seems to be a regular on FCL, why didn't he set a time for "dine on demand" ? He wouldn't have waited.
3/ "Non touch screen" ? Is OP sure it was not simply malfunctioning ? It happened to me once, and, several times I suffered from a shifted pointer (the pointer doesn't appear where I touch).
4/ As for Evian, I fully understand OP's stance. Myself only drink sparkling Voss at the First Class lounge, and Perrier all other times. But, again, he could have informed FAs that he only drinks Evian, and not the lowery filtered drinkable water such as Mai Dubai.
5/ As for sugar, OP is totally free to add sugar to hot chocolate, as well as I have a good friend that drinks lots of sugar with a small hint of coffee. It's OP's right to have a heart attack, as long as it is not on one of my flights.

And, finally, I'm amazed how many posts this guy triggers in few days. Just amazing.
