TOD. It makes me crazy when someone who is in a service industry such as a cashier or customer service person of some kind says "no problem" in response to "thank you".
What happened to "You're welcome" Or "my pleasure" ?
Now if some random person (not AAA) was to stop and help me change a flat or a friend was to drive me to an airport or help me move, that is a different story. In the latter instance I am creating a problem, in the former, they are just doing their job
