So i was in Costa cafe and I paid for LAN. The time was going to end in 5 minutes but i found this pretty idea to bypass the time and stop it.
1) Download Process Explorer.
2) After downloading, Open and look for "Client.exe" & "Guardit.exe".
3) After you find them, right click on "client.exe" and click Suspend.
4) Do the same thing with "Guardit.exe".
NOTICE:- The time is stopped now.
If you would like to resume. Right click on them and click Resume.
Thanks for reading.. Just whenever you do this don't show it to a worker :P
Now you have Unlimited time.
