The vest vending machine at San Francisco's airport may be mockable--but it's a money making hit.
According to a San Francisco Chronicle report, the vests are part of the unofficial uniform embraced by many Silicon Valley venture capitalists (who prefer arm ventilation).
A spokesperson for the airport telling Business Insider, the machine averages $10,000 a month in sales. The machines are selling about 200 vests a month, at nearly $50 bucks a pop.
This is not the first time the airports had clothing available from sale from a vending machine.
Japanese retailer Uniqlo started selling cloths out of vending machines in airports and malls across the US last year.
