Letting Off Steam Over Ice

(Though I usually get along well with my coworkers, there is one who rubs me the wrong way.)

Me: “Hey, [Coworker]. Could you dump this in the machine please?”

Coworker: “Why?”

Me: “Because I hurt my shoulder and can’t pick up the bucket with one hand. If you don’t want to do it I’ll ask someone else—”

Coworker: “Well, when did you hurt it? I saw you pick up a bucket of ice yesterday.”

Me: “Three days ago, and that bucket was empty. This one is full to the top with ice. Just forget it. I’ll ask someone else.”

Coworker: “No. I’ll do it after you admit you’re just being lazy.”

(I decide to ignore her and turn to ask someone else for help when another coworker stomps up and throws the ice in the machine.)

Other Coworker: “THERE! Was that so d*** hard? Next time someone asks you for help either do what they ask or tell them no. Don’t waste everyone’s time by trying to pick a fight. Nobody cares!”
