I'm a tipper, but some of the places I'm asked to rip don't make sense. I just deleted a thread with a picture, because I noticed the place put their name in the tip section.
They make a great product, and I like them. But... tipping for an online purchase?! Nope. I can see why people have started refusing, and I don't agree with that. But I think this over saturation of ripping was intentional.
It strikes me as a reflection that we're tipping (<--haha, but it's not funny) from one type of society to another. We grew up in one where we considered ourselves participants in a larger group, that our prosperity was ultimately tied to that of everyone else, and that we were gratified by being gracious and generous to one another.
Now we're devolving to a society where other people are means, not ends. We try to "get over" on each other. The sum gets asymptotically closer to zero.
There have always been people that viewed others as a come up. It was easier to avoid that type of person. They weren't nearly as common as they are theses days.
