That's brutal, @the_ray. Sometimes it feels like they only look at the font size and nothing else.

My mom's potato and leek soup is the best. Just boil them with some broth and blend it smooth.

Tell them it's the only part of the bike that touches two other moving parts thousands of times per mile. A worn chain grinds down your cassette and chainrings, turning a thirty dollar fix into a two hundred dollar repair real fast. I just say keeping it clean and lubed is cheap insurance for the expensive stuff.
