I completely forgot. I was thinking of where I picked up "All Day", and because every always seems to know what it means I thought I probably picked it up at a local game.
Even at the recent game, playing with someone I've only played with once, they said how much, I said $40 All Day, and they instinctively knew. Or maybe they thought that I was just being me and not answering
Anyways it just hit me. It's a term that was used back in my serving days to mean all included. Like how many salads for table 7? 6 all day chef!
