This thread reminds me of my first visit to the UK to meet my now husband in person for the first time. He couldn't pick me up at the airport so I ended up traveling by several trains to his little town. I'd already spent hours on end at an airport here and then the flight, then more hours traveling so I was more than ready and in desperate need of a shower. I booked into the little B&B I was going to stay in the first few days and couldn't wait to take one. I tried and tried, but there was nothing I could do to get hot water to come out, just ice cold. I was trying to hurry and finally had to give up. I took the quickest, coldest shower ever.
Later that night I told him I was going to have to talk to the gal that ran the B&B and let her know something was up with the hot water when he started laughing, laughing to the point of tears running down his face. He walked me into the bathroom and flicked this mystery switch on the wall and voila! Hot water! I had never seen or even heard of a hot water heater above the shower tap. Boy, did I feel like an idiot, but was so glad he'd told me before I had a chance to complain.
Now, I don't want it to sound like he was laughing so hard just over that as it sounds kind of mean, but I'd just finished spending 20 minutes trying to work the electric kettle in the room, only to discover you had to turn the electrical outlet on

He was super sweet about it, he just really got a laugh out of it. I did too! We still chuckle now about it.
The toilet in that room was terrible though. I couldn't get it to flush, not once. Talk about getting to know each other, nothing like having to have someone else help you flush a toilet. Good thing we ended up getting married
