Man that stinks, twelve bucks and two weeks of silence is a rough combo. Living with people who just quietly take your stuff and never say a word is its own special kind of lonely, like you're sharing a fridge with ghosts. Labeled shelves won't fix it either, they'll just steal from the shelf with your name on it and act like the label was invisible. The group chat rule only works if people actually care enough to be a little embarrassed, and it sounds like nobody there does. Keeping your food in your room is a pain but at least you stop paying for other people's dinners.

You really think twelve bucks worth of scrapers is the answer here? Half your time savings probably came from finally paying attention instead of from the tool itself. Scrapers only get you so far, a decent wire brush on a drill will eat that crud out of the tube holes way faster once you get the hang of it. Foreman was a jerk about it but the guy wasn't wrong that your prep needed work. Tools don't fix technique, they just make bad technique a little quicker.
