Imagine a man, let us call him John, looking like he has gone too long without a shower and is dressed in a torn T-shirt, frayed jeans and a pair of worn-out shoes. If John were to try to enter the opulent Village Market shopping mall, he would likely be denied entry or frisked a lot more than strictly necessary.
But if John had an Internet-enabled phone and went to one of the ever-growing online trading markets, he should be able to do some window shopping without facing any judgement.
