Trash can placement strategy and development

We have two trash cans behind the bar, one on the left and one on the right. As the shift is about to start I switch them. My bar manager declares,

"You're thinking too hard."

"No I'm not. I was just thinking that the trash can on the left is a lot heavier than the one on the right and it makes sense to have the heavier trash can on the right because when it's not heavy it doesn't stay in place."

My bar manager stares at me.
