Selling your plasma is big business

I often drive by this place, always notice it's parking lot is filled to capacity. In the early hours before it opens, there is generally a line out the door about 100'. I wanted to share this with everyone because it strikes me as one of the last ways poor people can subsidize their income. Generally the patrons in line look a scruffy mess. Betting they are homeless. You gotta stop and wonder why Plasma banks and "we buy your gold HERE" places are thriving. Also repo men are busy as a one legged man at an ass kickin contest.
