Howdy!
  Last week, I got my ss back from it's annual service... sadly, I didn't really have time to ride it, so put it in my garage and didn't really enjoy it... (funny story actually, they found mouse droppings in the air filter 

) anyhow... 
 Today I decided to goto work by bike given the sunny day, (a very short ride, only a minute long ride at most). Halfway there, I felt a judder from the bike and about 200 yards on, I noticed my rear caliper boucing on the road! 
 I stopped immediately had a look around (walked back to look for the two retaining bolts - and couldn't find anything). I eventually, put the caliper over the exhaust and got to work where I parked the bike and immediately called the garage. 
 While I didn't blame them outright for forgeting to put the bolts back (I was polite and courteous) I do believe they forgot to refit the bolts. 
 They're collecting it tomorrow; but I'm concerned. I've been told the brake lines are probably shot as it's dangled behind the bike for 200 odd yards by a friend who knows alot more about bikes than me. Also, the caliper is not scratched and the brake reservoir is overflowing brake fluid. 
 Question 1&2: is the line likely to be damaged? The caliper? (beyond visible scratches?)  
 Question 3: would it be unreasonable to ask them to replace the bolts, caliper and brake hose given the damage sustained? 
 Any advice?
