Well maybe he is slow. I haven't really saw a difference with workers age wise in grocery stores.
I'm Gen X and I do jobs dirty. Last job that pissed me off I left in the middle of an ERP integration. Told the manager that he better pray he never bumps into me in them streets
I'm a straight ass hole to jobs. Since I've been working remotely I play around with jobs in my local area. I'll apply and ghost them when they want to set an interview. If they are really close by. I'll even go to the interview. They will offer the job and I'll ghost them.
Look at the shyt they pull with people. I only do what my job asks. I don't volunteer to do shyt. I'm there for a paycheck and that's it.
I clown Gen Z but they are spot on about the workplace.
