When I've gone to LJS. I bring. 4 for the house. I then leave $ sitting on my pants (covered with my shirt). If they want pre-payment, I just move the shirt and all is good.
I figure with LJS. I'm in for $. 4 - no more. To me. That is about the same as the notel Asian ads. But instead I'm not driving across town and I know what I am getting - to cure the Yellow Fever.
One time I had a girl demand $. 2 - but laughed and told her "maybe next time. ".
Also. My advise for LJS. Is don't stand there pulling bills out of your wallet or from a roll. Instead. Have your set amount and have it ready. To me. It isn't a negotiation. It is a transaction with a set price.
But yes - much better value to be had for a little more effort...
