The people retailing food at the festival were in a unique position. Major name festival retailers - with the kind of experience you'd need to deal with a festival this big - were wary of dealing with the organizers for the same reasons the band were, unimpressed by their lack of knowledge and questionable forward planning. For that reason, a firm called 'Food for Love' were contracted in. 'Food for Love' had never catered for anything even a tenth of the size of Woodstock. It was always bound to end in disaster, but they made it worse.
Seeing that they had a very hungry, captive audience, they jacked up the prices of their hot dogs and burgers from a reasonable 25 cents to a dollar a time. To say that the hippies didn't like this naked capitalism is an understatement. They voted with their hands - and burned the stalls down. The moral victory was theirs, but the food burnt with the shacks.
