I was in Wetherspoons. I know, but this one is in a nice old building, has a good outdoor space and is generally frequented, during the day, by retired couples. I went for breakfast, it being one of the few reasonably priced places locally where you can get a healty breakfast. Porridge, fruit and yogurt for me, plus refillable hot drinks.
An elderly man came in, picked up an abandoned cup from another table, empties the rains of the pre ious cup onto the carpet and went to used the refil machine.
He wasn't loud or smelly and I should have felt sympathy for him, but I was revolted. Really disturbed, especially by seeing the puddle of cold coffee on the carpet and the way no one, staff or customer (including me) gave him any care or attention.
