100 homeless traveled to line up at an Apple store. Why? Because they could make $80 for a businessman who promised to pay them $40 for each iPhone they bought. Unfortunately, after the long wait, the deal's off when their "boss" kept bragging about his scheme. No sales to the homeless, no commission for them either. Some of they were stuck without transportation back.
Is the businessman ethical? I would say he should have given a notice of warning to his hires, should the store stop his scheme. So, he's greedy and dumb enough to not see this one coming.
How about the store, do they have the right to refuse the homeless? I believe any store has to right to refuse sales to certain customers, provided they have ethical reason. In this case, they are protecting their reputation: Who would want to compete with the homeless for being the earliest in line?
To understand further, I need to research about Black Friday, I think.
