Earlier quoted context omitted.
"Ope" is in use in Australia? Sandgroper here and I've never heard it before. Is it only in certain cities, or a generational / social group thing? Or do I just need to get away from screens more often?
It’s probably just me. Tend to pick up things I’ve heard once somewhere. On the other hand, I hadn’t heard sandgroper before and had to search to find out it meant Western Australian. Although, I definitely don’t get out much.

But saying sorry as a pre-emptive "oops didn't mean to step in front of you, mate" (when the other person had clearly walked into you), that has existed in Perth as long as I can remember.
