“Ok, fine, £70, but this better do the job.”

“It will man, just, be careful, some people say the strong stuff makes you see the future, and not the bits you want to see either.”

“Look, I read about it on snopes, it’s an urban legend, nothing’s been proven.” He was really committed to this sales pitch.
