Re: Drink water?
That reminded me of being on holiday (or business trips) with fussy eaters.
One time, on a skiing trip in the Swiss Alps, and one of the group would only eat either burger and chips (and the 'chips' were European-style, so not like the ones back home), or pizza (and the pizzas, being stone-cooked in a wood-burning oven, were distinctly nothing like he got from Dominos or Pizza Hut). The second time we tried for pizza with him, he decided to be 'adventurous' and accidentally ordered something which had a raw cracked egg put on it once it came out of the oven.
Another time, with a stand at an Expo in Vienna, the guy I was there with firstly didn't like the hotel breakfasts, because there were no Kellogg's cornflakes, the milk was 'different', and so was the 'jam'. I leapt ravenously at the usual options of dark rye bread, cooked meats, and scrambled eggs.
The first night, with his indecisiveness, I discovered this basement restaurant with bench tables where no one at all spoke English. All the locals ate there, and it was bloody beautiful. But he didn't like it, so we agreed we'd alternate on where to eat. Except all he bloody wanted was to go to a Chinese restaurant!
I said: 'We're in Vienna. I mean, Vienna. It's two weeks to Christmas, and everywhere is overflowing with what makes Vienna Vienna at Christmas. And you want to get a bloody Chinese? You can do that back in England. What's wrong with you?'
That night, we had a mediocre Chinese meal (crispy duck and pancakes) in a place that had somehow distilled the essence of Chinese stereotyping into a pure concentrate, and applied several coats.
When we came out, he said: 'You were right. That place last night was better.'
