I've made a stupid mistake at a company event (nothing to do with work, but the whole crew was there).
Here's what I did: I've decided to stream an event using a live stream from the Internet and a projector. Sound was choppy, picture was grainy and laggy, and the stream cut off in the most important second. Turnout was greater than expected, so some folks (in particular small ones) couldn't see from the back.
Here's what I should have done, retrospectively: Use the good old SAT TV. It's a bit smaller, but it's high up right under the ceiling, so everyone could see. Sound and picture were superb. Some people did turn on the TV, but I told them to turn it off again.
Basically, my mistake was that I thought I (non-technical) knew better than some (technical) people (those who used the TV), and that I even scolded them for turning on the TV.
Obviously, that didn't go well, and about a dozen people seem to have cut me out. They stopped greeting, don't recognise my presence and generally start talking in a rather sarcastic manner to me when they need something from me. This makes my job (office receptionist) rather difficult.
How do I gracefully get past this? Do I apologise to them in person? Or do I just simply craft a catch-all company-wide email, and let it be?
