background info: i've never owned a bike with a chain and up until yesterday had never cleaned and lubed a chain.
last week i was riding in the rain and knew i'd have to clean and lube my chain before i went for my weekend trip to the mountains. at a stop light someone pointed out that my back tire was flat. i pull over and saw that it was pretty low on air. so i get to a gas station, fill it up and limp to the local bike shop. i really wasn't planning on buying a tire (that one only had 1500 miles on it

"it's that much because you have a chain. with a chain we have to clean it, lube it and adjust it when we put the new tire on."
i thought, "great. now i don't have to do it before i head out for the weekend."
when i got my bike back my chain didn't really look any different. still black and looked like it had road grim/dirt all over it. but i thought, "well, all the chains on my bicycles growing up were black. maybe this one is too."
i discovered yesterday that my chain is very silver. not only that, but so is the rear sprocket (which i also thought was black). and i'm pretty sure they didn't do jack with my chain. now maybe there's a lube that they use that's like a thick oil that is black and they really did clean and lube the chain. but the lube i used yesterday was clear and my chain still looks silver.
it ticks me off when someone tells me they're going to do something and don't. sadly, i didn't know enough about cleaning and lubing a chain to be able to say anything that day. the other thing that stinks is i'm looking for a shop to be able to take my bike to when it needs things done that i'm incapable of doing. if i can't trust this shop to clean and lube a chain ... how can i trust them with anything on my bike?
end of my rant.
