What's the difference between quality sampling and quantity sampling for sponsors?

Joe Parsons explains that Monster prioritizes quality sampling over quantity sampling. Rather than mass sampling in front of a grocery store (which just makes it 'a product'), Monster prefers finding where their target audience hangs out - like bringing pizza and Monster to where BMX kids gather on Friday night. The goal is to 'be part of the good time' so when people are having fun, they remember the brand. As Joe puts it: 'We're not selling a product, we're selling a lifestyle. The product just is in the can - that just generates revenue.'
