Had a very "handy dad" moment today

Went to my local college town coffee shop and noticed one of their bathroom sinks was running continuously. I used my dad knowledge to figure out it was the hot side stem leaking and shut the hot water supply valve off, so the sink works now they just don't have hot water. I explained the problem to all the teenage baristas and felt very competent and smart.

Sorry just wanted to toot my own horn.
