Another time a deli worker at the grocery recommended a good turkey flavor, when I saw him next (it was weeks later) I made sure I told him how much I enjoyed it. I then told someone next to me (unsure of what to get) how the man put me on to a delicious flavor (boars head sausalito FYI). I still say “how are you doing sir” when I see this man working and I’m shopping. He remembers me even masked.
All of this really just involves taking things you notice and instead of keeping it to yourself, sharing it! It’s worth doing! I don’t do it for any selfish reasons (except maybe to keep my observation skills sharp). I genuinely feel an appreciation for sharing things I notice about others as they live their lives. My only hope is it makes them feel good about themselves.
For the facelift example, you notice it, and then remark about how youthful the director looks in that new shirt. For the shoes example, you notice it and then remark about their good fashion sense. For the hair example, you go to them and see how the home life is going (colicky kids, a new medical diagnosis, a death in the family, or pure unawareness, etc)
It may seem like 'pandering', but only if you do it to people who can give you a raise. You have to do it for the janitors, bus-drivers, and bar-tenders too. Because you want everyone's life to be a bit better that day.
It's kinda like being a culty-mad-scientist. You have to have all the knowledge, the years of experiments, the cash flow, the ancient texts, the elaboratory. It takes a lot to awake the elder god from it's slumber. But the most crucial step, and the last one at that, is the smarts to know to not to wake up the eldrich world ending demon at all.
