The people who came to fit my new integrated fridge found when they were about to leave that they had failed to attach the handle to the fridge door in two places (although it was properly attached to the cabinet door when they arrived). They were about to leave with the handle dangling and claimed (despite my telling them this was not so) that the handle had not been properly attached when they arrived. I said they couldn't leave it like this and they looked around, found the screw that they had dropped, took the door off re-fitted the door and handle to the fridge and all was well. So, the result was fine, but the speed at which they were working (also fine in itself) led them to be careless about looking after the screws they were removing - and then to 'head for the door' while taking no responsibility for what turned out to be their error, without seeing that I had a proper functioning fridge, seemed to me discourteous and perhaps a system error if you are encouraging your fitters to work at such speed that errors and discourteous service become more likely. Apart from that, straightforward.
