I used to manage a pub, and I hired an 18 year old chavy kid as a glassy and this is how he talked to me. Ngl, it felt pretty cool. I liked talking to him.
It was a big and very busy pub so we had both glassy and bar back. Usually that's the same person but we needed multiple people just constantly clearing the floor and washing glassware, and a couple people restocking the bar and changing kegs.
okay boss -> no need to argue, no need to talk about the task, just leave me alone.
you need to talk to the boss -> i am not taking responsibility for any decisions that if they go wrong will be blamed on me and if they go well i won't get credit for.
