I left a job on not the best terms and didn't realize that I still had a shipping address set to that location in eBay (or PayPal, I can't remember which). When the item didn't arrive at my home I had to track it down, and then go pick it up at my former job. There was a bit of awkwardness as they thought it was something I ordered for the company before I left, and besides, I didn't even want to be there. Just an uncomfortable situation all around but it was eventually sorted out. After that I made a point of becoming familiar with how eBay and PayPal work.
