It is a bank and it is the main branch. The main floor has over 10 banking service counters. When I am the next in line to be serviced, I always have to keep looking to the right and to the very far left end just to keep an eye the whole time to know when I am called next to the service counter. Some bank representatives at the far end need to walk all the way to the lineup entrance to grab the customers because we are never able to notice which counter is available most of the time. Why don't they install the indication light so as to make the service more efficient?
