The Shake

“I used to work at Steak ‘n Shake throughout college. There was a whole week that a man came in and got a table for two then waited hours before getting up and leaving. By about day 5 she finally showed up, ordered a shake and left.” – Reddit user E_berries
Did this guy forget when he had a date or did she stood him up for an entire week, only to finally show up for a shake?
