<p>i checked out of lab today, and didn't have my locker card. do they really need that back? will they haunt me until i give it back? is the chem 3al stockroom still going to be open this week even though there's no lab? because if they aren't open, how am i supposed to return it?</p>
<p>my GSI said that you could return the card anytime until the end of finals, and that the stockroom would be open.</p>
