It's certainly a very interesting case. But you say the car has undergone and passed the MOT test so it must have been working then, it would appear that whatever has happened would be connected to the service afterwards which they were not instructed to do by yourself, OP.
However, I'm afraid things aren't always that straightforward. Many years ago a friend of mine had a Ford Granada Mark 2 with a 2.8 litre engine. One day he took it to his local Ford Main Dealer for a service and MOT. Unfortunately, when he arrived, there were no spaces left in the dealership car park to he parked it on the road outside. He then went inside and spoke to the service reception staff and, by then, there were a couple of parking spaces within the dealership so they suggested he move the car before he left.
Anyway, he went back to the car and, guess what, it wouldn't start! He returned to the service desk and informed them of this. They told him not to worry, they've bring the car in themselves and see what the problem was.
It turned out that there's a fibre gear inside that engine, I believe it drove the distributor, and it had broken! It's a well-known fault on that engine, apparently. He was informed it could have broken at any time.
Now, if that gear had broken just the next time that the car was driven you can probably begin to see what possible problems there could have been between my friend and the dealership.
I'm not saying, for one minute, that this is the case where you're involved, OP, but it does show what can happen.
