I believe that it is an insinuation that all of the people in this thread who actively take drugs will inevitably work at Papa John's.
I wouldn't put it like that.
The way I see it, all the title really implies is that the decision of working at Papa Johns would be a choice that is naturally inclined for the lifestyle of people who also actively take drugs. From my personal experience, the two practices are rather compatible in theory (in fact, the concept probably could go both ways even), but that doesn't mean I intend to work for Papa Johns any time soon.
Whether or not anyone actually does is all up to them. There will always be variables involved, it's just that the choice they end up making doesn't change the fact that it still would be more likely to be advantageous for them if they indeed went with Papa Johns.
