I’ve experienced a fair bit of customer service over my time, and one thing I’ve noticed over the past few years is the increased use of the phrase, “not a problem,” eg:
JB: “Thanks for your help.”
Customer Service person: “Not a problem.”
Why can’t Australians say, “You’re welcome.” ??
My theory? Something to do with being laid back and friendly, rather than acknowledging a more formal, “I’m-helping-you-but-I’m-not-your-mate-and-therefore-I’m-not-your-equal-in-this-converation-so-I’m-going-to-keep-things-egalitarian-because-although-we-don’t-have-a-class-system-we-really-do-and-you’re-not-better-than-me-just-because-I’m-serving-you.”
How’s that for a theory?
Mind you, it could also be because these customer service people haven’t had good training.
