Is it possible to start your freelancing work at High end cyber cafes?

Conditional yes. I mean if it’s part-time then definitely.

You just have to find the right gig to start earning. Also, manage your schedule well so you can optimize your time when you stay at these coffee shops to work. That means you have prepared a list of what you need to do when you have the network connection or you have already done those things that you can do without it.

It will be challenging and not easy but not entirely impossible. But you also have to plan how to scale up. That includes having your own internet connection.
