Just curious... what algorithm does ren'py random choice use? I have this feeling in my gut that it's sometimes not random enough... that or I'm just lucky (unfortunate) enough...
Here's an example... see screenshots

Where is everyone?...

I use ren'py choice [a] [d] with [a] customer appears and [d] customer not appears... should be fine but I've been getting a lot of these straight no customers from dawn till dusk lately and in one occasion twice in a row... each turn is random ranging from 2 minutes to 6 minutes... for now, the only solution I could think of is increase the random choices. A bit farfetched but is there a better way to generate random numbers?
Hm... renpy.random is a wrapper around python's random module that generates the same random values when rollback occurs. Python's module uses the MersenneTwister algorithm, which is pretty damn good pseudo-randomness. Here's the result of rolling a 1d6 a million times:
Probability can be a bit confusing, as unlikely events do happen, especially when you run enough trials. Realize that there's enough meat here to make a college subject.

Is it possible that something in your code is making it get stuck in the same choice? Also, if you want to make sure the user can't get too many instances of no customers, you could try writing the code to self-correct any anomalies. this would definitely help people like me who tend to have bad luck in games of chance on the computer... Of course, to do that you'd need to use renpy random randint and base everything related to it on a variable with an upper limit.
