I had a similar situation some years ago, prior to getting my CHL. I was living and working in California, and a buddy of mine and I had joined an indoor range in Bakersfield to keep our skills up until we got back to Texas. We had to rent our guns from them, but it wasn't that bad at all. Anyway, we're in the booth, with a B-27 target down range and I picked up the Walther P-99 we had for the day (too bad only 10 round mags in Kalifornia) and ripped off all 10 rounds. It was two sets of three, and one of four, pretty quick like, but not panic fire or anything. The "range pro", an off duty LEO, come up and says, "I see you're shooting a handgun, at a police style target, so I guess you're practicing for self defense?"
"Yup"
"Sooooo....why would you empty the entire magazine all at once?"
"Well, he never fell down, seems like still a threat to me, so I kept shooting, besides, I gave him a half second or so between shots to fall."
He laughed and said, "You boys are from Texas huh?"
Turns out he was too, we struck up a conversation and became friends. He'd give some pointers, we'd listen. That was a fun summer.
