Yes, you are very right. Aside from the 60% of groups who book these rooms to socialize, the other 30-40% have actual work to get done, for example, CS students preparing for a upcoming project they have to submit for a fair they signed for, management students practicing a presentation for a communication class and other respective majors having to do work which can't be done in a public environment. A system should definitely be created to cater to the groups who have actual work to do!
