I have discovered, much to my dismay, that the outbound mailbox in the lobby of my new office is not actually in service. Apparently there used to be a sign on the boxes that said this, but the sign got removed, and the door to the box opens, so it's physically possible to drop letters into it. Which I did earlier this week, including a bill payment. Arrgh! Fortunately, I pay most of my bills electronically these days, and this happened to be an extra payment I was making by check because the e-billing system in question couldn't handle more than one payment a month. The facilities manager has been alerted, and they're going to try and catch the mailman when he comes by this afternoon and see about getting into the box to collect the otherwise dead letters -- and then they'll see about sealing the box to stop this from happening again.
I wonder how many of my co-workers were similarly nailed by this.
