Rice Toppings

I have four back-to-back classes in the afternon today, so I ordered a box set lunch (bento) from the cafeteria. Today's menu was pretty good (a lot of veggies and meat - I get special boxes without much fish or anything deep-fried after I got sick from eating a bento with a deep-fried mussel last year).

Anyways, we always have a big compartment with rice in the box, but today, they gave me a little packet of sesame & poppy seed mix to pour on top of the rice. The mix is pretty common here and I really like it, but I just have to say... does anyone else think it is strange that they are feeding the staff poppy seeds when we have to take urine tests at school tomorrow??!! I think they are just testing for illness tomorrow(not drugs - my friend had to submit a stool sample for illness at her school - yuck), but I am pretty sure any caf staff in America would think twice before serving poppy seeds, which have a reputation for messing with urine tests (right?).
