Honestly, it depends on the person and the purpose. If you have a clear goal, like buying something specific, shopping can be very efficient and worthwhile. But if you're just window shopping or browsing without any intention to buy, it can end up wasting a lot of time. That said, for some people, shopping is a way to unwind and relieve stress, so in that case, it's actually a valuable activity for them. It really comes down to personal habits and what you get out of the experience.
