Some of these are amazingly cheeky, but I think the Mexican holiday home is still the winner.
A long time ago, just after we were married, we wanted to go on a skiing holiday. We didn't have much money to spare so wanted to do it as cheaply as possible. We decided to book a self drive holiday as it was much cheaper than flying. We had met a couple who had moved to the area, and as the wife had never seen snow (they were both from Africa) we invited them to come too. The husband had an extremely well paid job - this is relevant.
After checking the brochure and working out prices, they decided to come. We agreed that we would share the petrol costs, although DH and I would do all the driving.
We filled the car up with petrol and set off. At the next petrol stop, DH filled up and went in to pay. I had been asleep, but was just waking up to hear the couple arguing quietly in the back seat. She was saying that they should go in and pay as it was their turn, he said he had no intention of paying for any petrol. It was a bit awkward to say anything so I kept quiet, but decided that I would remind him next time we filled up that we were sharing costs.
All went well until we got to the Swiss border. This is where it gets complicated. The other couple were from an African country, but the husband had Irish grandparents so he had a dual passport. The wife only had an African passport and had to pay a small amount beforehand to get a visa to travel into Switzerland. The husband told us he didn't have to do this as he was travelling on his Irish passport instead of his African one, although he had brought both with him. What he didn't tell us was that his Irish passport had expired, so he was travelling on the African passport with no visa. We had huge problems at the border, there were guards there with guns, and we didn't know if we would be allowed into the country. Eventually they let us in, and we drove to the hotel.
All in all, we had a good week. The wife was lovely - the husband was annoying. I have never met anyone so mean in my life. There were little things all week that got on our nerves, but we tried to ignore it.
We were all being careful with money, so just had one drink each night with our meal, and gave our room number. DH had a beer every night, I had a diet coke every night, the wife had a glass of wine every night, and the husband had a glass of tap water every night. (He made a big fuss of ordering 'tap water' every night).
At the end of the week, we were given our drinks bill. Ours was for 7 beers, 6 diet cokes, and a glass of wine. They had obviously switched one of my cokes with one of the glasses of wine, but we thought that it didn't matter, because there wasn't much difference in price, so we just paid it thinking they would do the same. However we found out later when checking out that we had to pay for one glass of coke. He had been given their bill, for 6 wines and a coke, and had told them to put the coke back on our bill but not to put the wine back on his! When we questioned him about this, he actually told me that I had had a glass of wine on the first night, and must have forgotten about it. This was very unlikely, as I don't like wine, and I was not impressed with him at all.
There were lots of other small incidents throughout the holiday, just petty meanness, and by the end we were very glad to get home.
Sorry, that turned out a bit long!
