I feel like serving shows you the patterns of the universe

Very dramatic lol, but seriously! I'll have 3 days in a row at my restaurant where everyone wants the pork chops, or something very specific that just seems to be ordered more frequently than usual. Like this week, on Wednesday I had a lady order orange juice and I hadn't served anyone orange juice since i started working here 2 years ago (steak house) I wasn't even sure if we sold it outside bar drinks. Now, i've had at least 1 table in a shift since then order orange juice. Are we all a collective mind or do I really need a vacation?
