Bad tempered staff and manager who does not care in the least

Six of us went to Cafe Paul Melrose Arch today for lunch. We arrive between 13h45 and 14h00 and sat inside close to the kitchen window. The service has been slipping these past six weeks but today was a catastrophe. The waiter took the orders incorrectly, instead of 2 salmon salads he brought only one and the proceeded to argue with us bout this. The young waitress who was charging her phone next to our table and kept going over looking for messages repeatedly looked at the table and tried to remove half drunk coffees and unfinished plates. But then the best came. One waiter pulled out the mop and a very strong smelling bucket of water and began washing the floor around us. He kept bumping into our chairs and bags and in the middle of our lunch we were scrambling to pick up our belongings. No one even offered a Spare chair to put these things on. We were then brought the bill without even asking for it…. There is a bad mood amongst the waiters, contrary to the staff behind the counter who are consistently sweet and helpful.
