"No problem" or "not a problem" suggests to the customer that if it were a problem, you wouldn't have helped them at all. Those phrases tell your customer that, from your perspective, the relationship is all about what is best for you and not them.
Again, it's really irritating to have to explain this.
No that's the implication you choose to imply to it since you were taught what would now be considered antiquated manners, often "no problem" reply to a thank you is given following things that are indeed a problem. I'm try to explain to you that it's cultural difference between yourself and those younger than yourself, they aren't in fact disrespecting you.. YOU feel like they are. I hope this clears this up for you and seriously.. stop with your ageism rants it's at best unbecoming.
