I have 4 laptops ( i'll call them L1, L2, L3, L4 respectively )
I have a wifi router, lets say I've to pay to use it..
Per connection it is, say, 2$.. Now I want to save money and I'll get only 1 connection. But I am also greedy, so I want internet on all laptops..

I dont want the owner to find out, so I'll not try connecting laptops with lan..
Now if the above scenario is to be solved, is it possible? ( I am not tryin to cheat anyone.. coffee shop owner is my friend and I've challenged him i'd do this.. so wanted to know if it could be done )
I thought of a solution as this :
1. I'd connect L1 to router
2. Get a usb wifi router and connect it to L1
3. make L2, L3, L4 to access L1 through usb wifi and share the internet..
does that work?
thank you
