24/7...NOT!

How can you say a business runs 24/7 when they still close on a specific hour?

Maybe this only happens in Sharjah so I don't know about the other emirates. There's a big supermarket chain in UAE called Spinneys. The branch along King Faisal Road claims they are open 24/7. BUT they close on Fridays at 12 nn and resumes at 1:30 pm.

You only happen to know this by accident. There is no signage that says they close every Friday on that specific time. Why? Because it is a given that you know it is the Muslims' holy hour of prayer. They just advertise the shop is open 24/7. So, if you're new and need to make a quick trip to the grocery, you'll be in bad luck. Then again, even if you're an old timer who never needed to shop on Fridays, you'll probably never know...until!

Misleading. Very.

What to do, yani? Go with the (inefficient) flow?
