........Coca Cola Old Vending Machine History.............................Glascock’s rudimentary vending machine worked on the honor system: customers grabbed a bottle of Coke from the cooler and then paid the cashier 5 cents . . . or did they? ............................................Pretty soon, both the company and retailers wanted a coin-operated solution................................................ Westinghouse produced the first generation of these coolers in the early 1930s, but Vendo quickly cornered the market with its full-size, upright Coke vending machines. ..................................................These began appearing all over the country in supermarkets, bowling alleys, and other businesses, and are now highly prized by collectors
