For the 1 all I can really say is don't be lazy. The map and town generation is how it is. If it was not for the stores being split up it would be 1 block of stores and a town of nothing. For the cars its a 10 minute timer to clean things up. If cars stayed for hours the server would be trashed on. So just access the inventory to reset timer. The paychecks are really only to help. Your supposed to make money. Its having a job and earning money to buy things. Earning money legally or illegally is up to you with different payouts could be dangerous or fun. Either way you can meet people or fight. Its always a surprise. 4 is something you would have to take up with someone else but keep in mind this is Arma 3 and a modded server.
Make sure you join the other servers though. Server 6 is kinda dead. Hop on server 1-4 and see how you like it if you haven't.
