They warned you about eating over top of keyboard
Up until recently, I was a computer tech. When I was working in DE there was a lady who called in saying her password wasn't working. We changed it, same thing. We logged in as her with no problem. I went up to her desk with another gentleman as it was a slow day and wanted to get a laugh out of it. We watched as she put in her password and noticed that when she hit a certain key 2 astrics would come up. Upon further inspection we noticed a "Gel" which kept two of the keys stuck together. We scrapped it with a knife and eveything was fine. When she asked what would casue that, we pointed to the dozen donuts sitting on the desk next to her and said have a nice day.
