Why no back-up power?

Why does the gym close as soon as load-shedding hits. Unfortunately this is a reality in the country and businesses need to adapt. I can understand certain equipment not being operational but there is no reason to not have enough lighting so that people can still use the weights and spinning bikes etc. Lastnight I was told they had to close because it was too dark. Seriously? Its not difficult to invest in some lighting, and maybe going solar would improve the image of the gym anyway. We're paying to use these facilities you could at least try to provide the service instead of just throwing in the towel and closing the doors.
