There's a Thief in Our Area!!

So, my manager counts my drawer and come to find out, another employee rang up their food on my cash register without paying for it. But, I'm the one who will get in trouble for it because I'm responsible for what happens on my drawer. From now on my manager has advised me to lock my drawer whenever I am away from my register, and to not allow anyone else to use my drawer, even during busy times. I'm angry another co-worker took advantage of my trust! Grrr....
