My project manager one time called me while I was waiting in the bank. He told me that the latest changes in the project I was working on were not deployed to production and they were having a meeting to demo those changes to the client later that day.

I had my laptop with me but it wasn't charged. I asked the security guys if I could use the socket used to power up the cleaning/sweeping machines and they didn't mind.

So it was me sitting on the floor in the bank hall using a side socket to power up my laptop holding my cellphone so I can use the hotspot and get internet connection deploying yesterday's changes to a production server.

Eventually, the client didn't attend the meeting that day!
