However, as I mentioned above, if you get the worn parts back there is no assurance they are indeed your old parts unless you know exactly what you had. I expect most riders can't identify the make and model of their old chain so showing them any beat-up chain will convince them it needed to be replaced.
or you can pick their pockets when they enter the shop, lol.
without a minimal ammount of trust, no trade or commerce can be done.
i'd never do business with someone i suspect would want to trick me.
charging for parts or work that hasn't been done is a very bad, very short sighted policy imo.
