throwing money away

All the bartenders behind the bar pool tips. Our tip jar is right next to the trash can. So when it gets busy, sometimes I'll accidently empty an ash tray into the tip jar, or throw money into the trash (which I definitely really watch out for!). But today at the end of the shift I saw a lonely dollar bill in the trash. Talk about throwing money away. That dollar is a whole Mcdonald's cheeseburger!!
