Hmmm, I was in Scotland and am now in Wales. It depends on which computer lab you're in where I am now- most of the ones with the new really smart computers in are quite strictly monitored for people eating and drinking and are kept very clean, but some of the others (like some of the 24hr ones) are a bit less well regulated, although there are signs up saying that no food must be eaten and that only screw-top bottles of water are allowed anywhere near the computers. I can't say I noticed any difference between the two unis to be honest- nothing has been so horribly dirty that I have actually noticed! Maybe I just have low standards lol! Best, KB
