It’s rainy and dark outside, and it’s not going better inside: another depressing day at MegaCorpMoneyMaker, the company you’re working for. Of course, you need to debug the 28925th bug of the day; some cursed prices made their way into the database, finally reflecting the real value of the low quality products the company is selling. Your manager, of course, doesn’t see this unfortunate change as positively.

These prices are imported from files you’re fetching from an FTP. You need to search through all these files to find out where the weird pricing is coming from, and you don’t really know how to do that without losing your time (and your mind).
