Oh. I'd be in a constant state of panic if I reacted like that. I've lost them for months at a time... But yeah, they always turn up. And I know they're somewhere.
I have a bigass jar of spare change on my desk, and a coffee canister for loose bills, but when school's in I tend to be lax about putting things in said jars. So they just stay in the outside pocket of my messenger bag.
I spend a lot of my time at the desk within arm's reach of both jars. The coffee canister only has any money in it for a few days, tops, before I get around to putting said money away.
