Swap out or change out does my head in, just say swap or change!!
“Regular” instead of “medium” does generate the urge to murder someone.
This annoys me as well, I went somewhere once and asked for a small something or other*, the person behind the counter actually said “oh, we only do regular or large”….I said, “I’ll have the smaller of the two then please”…..
*could have been a coffee or maybe a bacon butty!
