Turned Away

So I'm a big Coke drinker (Coke Zero actually). Anyone who knows me probably already knows this. For work, I've taken to buying 2 liters and keeping them in my office since we have ice readily available and then instead of spending about $1.50 per 12 ounces at the little convenient store in our building, I'm spending about $1.50 for a 2 liter that generally lasts me a week. The problem is that since I don't drive to work anymore, that means I either have to carry the 2 liter on my 10 minute walk to the subway (not very desirable since I'm not kind of a wuss) or I make an occasional trip to work on the weekends and drop off some 2 liters. The latter is what I planned to do today. A grocery store here is selling all its 2 liters for 10 for $10 so I stocked up and thought I would drop like 4 or 5 off at work. Otherwise, they sit in my car. I armed myself with four 2 liters and headed into the building carefully (that's heavy!) and when I got up to our office, I couldn't get in! We have three doors and the door entry code would not work on ANY of the doors. Ugh, I was so frustrated. Usually, the only time we change the door code is when someone leaves and considering I was at work until 6:30pm Friday night, I'm pretty positive no one just up and quit over the weekend. So what's the deal? I'm really annoyed. I came home and checked my work email and there isn't even an answer there. The only thing I can guess is that somehow the daylight savings switch affected it? Who knows? But I do know that all our office bigwigs are out of town until Thursday at a seminar so I can hope that this means we won't be able to come into the office for three days. Maybe?
