Acceptable service?

I'm with F5 Dave......

Say Bikeshop does check and fix everything NOT related to job done....it will have to charge for this.....and people will complain about that to..., so it's a no win situation for the workshop.
Same as borrowing something from somebody and it shits itself while you got it.......
You didn't cause it, BUT the owners sort of thinks you did.....so you sort of feel obliged to sort it out....

...why would a component work, and then not work once you put it back together again if you pout it back exactly the way it was?

Took it apart and lo and behold....rusty as!!! After a clean it's working again...

...

I never move the switch at all...headlights stay on day and night.
By turning the lights off they moved the rusty (but working) contacts and probably spread some rust across the patches that were connecting.

Who'd fix bikes for a living?

All cheap things are like that - disturb them and they freak out. It's no ones fault except for the person who didn't spend enough money on it to begin with, but we are all guilty of that also.

Ya pays ya money and ya rolls ya dice.

So it was working when he took it in. Is it unrealistic to expect it to be working in a similar fashion when he picks it up?

This happens when you put it back together INCORRECTLY, why would a component work, and then not work once you put it back together again if you pout it back exactly the way it was?

one possible, in a nutshell is static burn.
Electronics ( specifically CMOS technology IC's) really do not like static, and will burn out quite easily, without any external signs of this. If you work with these, you learn how to handle them correctly without frying them, but even then mistakes, and stuff ups happen, and its nearly impossible to tell until the component fails.
And to make it worse, it doesn't always fail right away, it can simply "age" a component, making it more likely to fail sooner...

This is of course assuming the problem is electrical in the first place, rather than mecanical ( swtich contacts etc) so .. thats my 2 centidollers :P
