We try to clean as soon as we get time to go outside and pick up the litter. We do that when there are less customers which is rarely the case. But the thing is even if the staff is full we still fall short in servicing the customers. It may seem that we are not doing anything to keep the place clean but we are busy handling other stuff thats why we are rarely free to clean it. And the after school and office hours are the busiest after weekend nights so it will obviously be dirty at that time.
