Whilst it's not quite as bad for people dossing overnight (despite the 25 to 30 departures between about 0645 and 0815 each weekday morning), unfortunately LTN also suffers from the 'chewing gum & discarded wrappers syndrome' and since the common denominator must be the lo-co operators' passengers, it's obviously got something to do with the calibre of the customer...
Combine this with a ruthlessly cost-focussed management (= low numbers of relatively low-paid low-motivated staff) and the question of whether 90% of the customers would either notice or care (presumably, if you're only paying say, £15 for a return trip to Rome, you don't expect anything better) and you can begin to see why such locations don't quite measure up on the international cleanliness scale.
Contrast STN, LTN etc., with LCY for example where 90% of the passengers are premium-rate business travellers who pay for and expect, something slightly more up market.
It's 'horses for courses' I'm afraid - and as MOL (or was it Gerald Ratner????) once said, to make money you just pile 'em high and sell 'em cheap...
