One opening barista calls out "sick" all the time then shows up later the same day to collect his tips and mention that he doesn't have COVID. Another coworker gets livid if I ask her to get an item for me when it's a task in her position. She also verbally abuses me.

Example:
I'm on DTR, she's on DTO. Since my position handles cash, I'm not allowed to touch drinks or food (unless I were to wash my hands first). My customer at the window has a bottle of water in their order but there isn't one on the counter yet. I ask her, "Would you get me a bottle of water?" She's literally standing in front of the fridge that contains the bottles of water. It's also where the DTO computer is. She rushes off in a huff just to physically demonstrate that she's not going to comply. One of the bar baristas annoyedly grabs it instead just to solve the problem she's created. Her behavior gets worse from there. She's now been fussed at twice for refusing to do her job. I mention over the headset, "Waiting on a spinach feta wrap at the window." Over the headset: "You're gonna be waiting for a while."
