At my university I'm taking a class where we need access to a certain lab. To get into the lab you're supposed to have a pass card to unlock the door. However the door is usually propped open and if it's not people always let each other in. I decided to buy a pass finally, because an assignment deadline is coming up and if I need to go there at night when other people aren't there it could be an issue.
I went to buy the pass card and the people in the buildings office sent me to the bookstore because that's where it's sold now. When I did buy it, I had to activate it online. When I did activate it, it said it takes 1 business day to process. This was on Friday and now I can't work on it over the weekend.
In general how do you prevent from these mishaps from happening? I moved from a large city to a smaller (and IMHO) more bureaucratic one and I find things like this often happen. For example, I would never have expected having to wait 1 business day.
Admittedly a small part of me didn't want to cough up the money to pay for the pass card and my friend gave me his but it didn't work anymore.
