I did it because on my first Sunday (last day of the working week, because it's closed on Monday, reopens Tuesday), the boss had gone away, left me in charge, and there were only a couple of part-time staff, who only work weekends, so they couldn't launder them and bring them back in on Tuesday.
So I just took them home to wash, because it had all been a bit of a blur/bit of a whirl starting the job, being quickly and minimally trained, then left in sole charge with part-time staff under me.
I assumed that when the boss was back, he'd take care of it. He was supposed to be coming in the following Sunday for a few hours, but in the end he didn't come in so I ended up taking them home again.
