No Problem...

Has anyone noticed how "no problem" has replaced "you're welcome" in today's vocabulary? I was at a restaurant tonight and asked for a refill of my iced tea (they give free refills). When the waitress returned with the drink, I thinked her and she said "No problem." Of course it's no problem. It's free. If I ever own a restaurant (unlikely) please remind me to train all my employees to say "You're welcome" instead of that awful "No problem". Even better would be "My pleasure", but I guess that's asking too much. By the way, I still had a nice time at the restaurant and still gave a good tip.
