I'm thinking of accepting a bribe to not sell someone cigarettes
What happens if you stop selling them?
I'll get fired and I'll be homeless. But I will have accepted a big amount of money from the bribe!
You are offered a bribe but might become homeless because of it. You should think this through, what is best for you in the long run? Bribe money won't last forever, but a job and it's benefits do.
I'm not homeless and I get by. Selling individual cigarettes for a lot of money is the only way I can survive.
Maybe you should not take the bribe then. You should refuse if you know that it is going to screw your life up in the long run.
