We were exhausted that night, as all the sites we wanted to see was blocked with queues that stretched for ever. So later we sat down on the grass on the Champs Elisee with a coffee from Macdonalds, and tried to build up some of our lost energy. We still had another day in Paris, and had decided to try and see the Tuilleries gardens the next day, hoping that the crowds there would be thinner than in downtown Paris. As we had another two days when we came back and before we flew to Heathrow again, we were not to pressed, but I knew that we were going to miss a lot of things we wanted to see.
 We did see the Tuilleries, which is absolutely stunningly beautiful, and then we went for dinner at a smallish restaurant at the outskirts of Paris that seemed not to be too commercialised. Of the menu, that was all in French, we did not understand much, and ordered something that was like priced reasonably, hoping for the best, as the waiter couldn't understand us at all.
We ordered a red wine each, and it was lovely to sit and watch the people, of which there were few tourists, most being locals out to just have dinner.
In due time our food arrived, and as we were very hungry, we tucked in without much ado. It was a kind of stew with potatoes and carrots, with a most beautiful aroma, and we were savouring every forkful.
I saw the waiter came down the tables with two plates of food, and put it down at the table across from us. I saw the couple look in utter perplexity at the food, then at the waiter, and the waiter standing smiling, I suppose also perplexed by their looks!
The man was quite calm, and I could see him talking earnestly to the waiter, who was standing like a salt pillar, his eyes rolling in our direction every now and then.
The next moment the woman went off like a bally banshee, pointing a very long finger at the plates, her eyes blazing and her voice like a razorblade, and the poor waiter, who was by now purple in the face, his eyes bulging dangerously, started walking to our table, and in a voice as small as that of a mouse, tried to ask us something. After a while we understood that he wanted to know what we ordered, and at showing him, he turned from red in the face to being ashen, and after almost tearing out his five remaining hair, he walked back to the kitchen, his shoulders slumped in a pathetic way, and we then at last realized that we ate the wrong food!
When the woman realized that we had eaten their food, she turned on us, and gave us a very good talking to, and meted against the embarrassed faces of the other diners, it must have been one pretty good scold! Luckily we could not understand a word of what she was saying, so we just ate on, with the rest of the diners's eyes burning into us, all of them by now worked up into hating us by the the woman whose food we unknowingly ate!
The poor waiter, still as white as a spook, came and took the food away, and in due course he brought the right food, and the whole restaurant calmed down, and we wondered if it was such a good idea to eat in the small restaurants where only the French ate!
