maybe because they don't allow you to eat whilst working on your pc on the weekends. I understand they are worried about squatters and need to turn over tables, but it's the afternoon, empty and I had ordered food and drink within 2 mins of walking in (meanwhile a group of 4 hadn't even ordered by the time I received my food). I had to leave immediately bc work deadline, didn't drink tea, had food wrapped up but should have left without. they have a sign, but didn't see, but who cares? I wasn't even using their wifi. too bad because I often visit them during the week and spend a bit of money each time. good luck to them but be nice if they gave some consideration for people who come in by themselves; wonder if it is OK if I was reading a book? they must have another reason for no pcs?....
