I've told this story before, but this is a genuine example of high-grade Dad embarrassment infliction. I was running a mainly pro audio sales operation back in the 1980s in central London, but we also stocked a certain amount of guitar gear. A lad of maybe 12-13 comes in and says he's interested in a practice amp. We show him the smallest amp we've got and do the usual 'guitar hero licks' demo. Of course, he loves it and says he'll be back with Dad. A couple of days later, the boy brings Dad in, who announces in a loud voice: "This is an amplifier for someone who is playing in a group. You don't need this. This isn't an amplifier for a little boy who wants to learn how to play the electric guitar!" Obviously, the kid is now squirming at being shown up in front of these guys who can play pretty good guitar. I was so sorry for him, I didn't say to Dad: "This amp is slightly more expensive than those tiny bedroom practice amps, but the tone is far better, and he'll probably still use it when he's starting to play with other musicians." No, I just stood there, totally aghast at what Dad had just done to him. What was so difficult about: "OK, but before you make your mind up, would you like to take me round some of the other music stores?"
