Apparently my current lab contains people who cannot or will not order supplies. As a result, we are constantly running out of certain regularly-used items. I know that this problem is not unique to my lab. On a good day, finding a certain reagent or supply completely gone makes me mildly annoyed. On a bad day, this can send me into a rage.
Yesterday, I found myself annoyed as I was having a decent day already. A couple other co-workers and I discussed the ongoing problem and potential solutions. My solution, regrettably, was to start hoarding this particular supply (one that I always need and we are regularly out of) for myself. I really don't like to hoard supplies, but I also don't like for my experiments to get put on hold because some dumb fucking donkey couldn't fill out an order form.
This ultimately lead to a discussion about people taking your solutions and reagents without asking and the remedies we each had employed in the past. (Note: I am NOT talking about a few mls.) My co-workers had tried (1) hiding solutions; (2) writing "DON'T USE WITHOUT ASKING" on the solution label and (3) giving solutions generic names such as "A." My remedies included making the solutions weird concentrations that require the thief to do math. (For example, 1.41M instead of 1M.) The hypothesis here being that if you are too lazy to make solutions, then you are probably too lazy to do math. If this doesn't work, I mislabel my solutions. The label may read 1M Tris, but it is actually 5M NaCl. This is most effective because the thief determines you can't make solutions and quits "borrowing" from you. I was told this was kind of evil, but I think taking people's shit without permission is still worse. Of course, I am an only child and I don't like to share. :)
