Is it just me or has society really regressed that much?

I had a really good upbringing as a child in South London, where I was taught right from wrong and about being polite. Politeness and courtesy seem to have become less common in daily interactions, and nowadays people seem so surprised when you are polite to them. There might be various reasons for this, for example, cultural shifts or changes in social norms, also, in an increasingly fast-paced world, people might be more focused on efficiency rather than interpersonal niceties. However, there are still many who value and appreciate politeness, this might not always be immediately evident, but small acts of kindness and consideration can make a significant impact, even in a society that sometimes seems to undervalue them. Contact me via e-mail and let me know about some instances where you noticed surprise when being polite.
