Add “(Today Only:)” to the start of every paragraph in “Happy Hour”, then add a new paragraph to it:-
(From Tomorrow:) If all prices on a Truck’s Menu are $6 or lower, then that Truck is holding a Happy Hour. Each Sale performed at a Truck holding a Happy Hour skips the “They look around” step.
Trying a simpler take on Happy Hours: they happen automatically on very cheap menus, and stop customers from drifting away.
