Weird news - Finding vomit on your airline seat

In the service business, quick turnaround is a necessity for earning more money, but that sometimes clashes with service levels. I once had to take a train, and it was a turnaround from another train that was supposed to arrive some time earlier, be cleaned and then take on more passengers. It was late so it was probably decided to quickly just let it be used again without cleaning, and that was what happened. The problem was, the inside of the train was pretty dirty, one is used to see a train after there has been some amount of cleaning. Similarly, when you take a cinema hall or a flight, it is typically a quick turnaround. If you spill some popcorn or soda, do you stop to think about how quickly they would be able to clean it before the next set of customers arrive ?
Well, this gentlemen got to see the case when the seat was not cleaned and got a seat with vomit on it, and with not much of sympathies or action from the cabin crew (link to article):

A British Airways passenger was horrified to find his seat covered in what appeared to be vomit. Passenger Dave Gildea was travelling from London Heathrow airport to Seattle when he was assigned seat 64K. "I had upgraded to business class at the airport in London Heathrow and was assigned seats 64K," the 38-year-old told The Sun. "I didn't notice anything until about two hours into the British Airways flight when I popped down the foot stool so I could get some sleep and saw the vomit on the seat. "It was also splashed on the wall behind and the floor below, which I then noticed." However, Mr Gildea says that he when he told the cabin crew about it, they asked if he had been sick on the seat himself. "I went to the cabin crew and the attendants first response was 'was this here when you boarded?' but it was clear it was dried in," he says.
