The customer had asked, as I walked up the garden path, whistling as I recall, “You’re not going to break the door are you?” I don’t know what terrible experiences they must have had previously, but the reason for calling a locksmith, rather than a passing rugby player, is that a locksmith opens your door using their bag of conjuring tricks. They don’t kick the door down. And if you called for a locksmith, but someone arrives carrying nothing but a drill, then unfortunately you haven’t actually been sent a locksmith. Unless you have a Bramah lock (or one of a handful of other very, very good locks), there are always several non-destructive things that should tried first, saving you the cost of a new lock (or a new door).
