If that's what you think, then cool!

Actually I used all four, but was prepared to fall back to 3, 2, or 1 in case anyone walked up, but it didn't happen.
The barcodes made it really painless...scan, press print, scan, press print (previously, it was: card, press reservation, press print). The only snag was remembering which one(s) I'd scanned. I numbered them, then spaced out and scanned the first one in the first machine, then the first one in the second machine, whereupon 'Reservation Not Found.' That's why you hear me say 'That's not it!' about 1 minute in.
