Just today my friends and I went to this printing shop near the university to print out some PVC IDs for our organization. It so happened that the shop required us to submit the JPGs in ready-to-print format if we want the IDs to be printed tomorrow. We have to have the IDs printed immediately because we will distribute them later, so we worked on every single ID on the spot--manually because we didn't anticipate this. We didn't have an ID processor software installed.To make the process faster, we distributed the work among ourselves so that one would edit the image files and one would dictate the data needed, so we set up an ad hoc network for this. All seemed quite well except for one thing. My friend's laptop was already low in battery, prompting him to plug in the store.
He didn't know if there was an available wall socket. All he saw was this puny extension cord with an old electric fan plugged into it. He removed the fan and plugged in the laptop. It was a particularly hot day, and the room was not well-ventilated so just imagine the sweat we produced while processing the IDs one-by-one.
Hours later, after producing pails of sweat, someone came in the room and plugged in the electric fan into the same extension cord. Looks like the extension outlet is two-sided after all! That's just the most amusing--and frustrating--event that happened to me today. However, I don't think I would be using the fan even if I had known there was an outlet at the back. The extension device seemed so puny that it will be subject to overloading anytime. It's very far from the power strips which we regularly plug our computers to.
