Oh tell me about it, what a joy! I only really discovered it a year or so ago.
Someone was staying over and I had a shower and was like “oh no, the plug is full of hair, guess I’m just gonna have to have short showers from now on.” And he was like “what?” And went to the shop across the road for drain unblocker and came back and did it and half an hour later he was stood there, shower running and draining perfectly and if memory serves me correctly I was clapping and like “omg! My hero!”
