By stripping fully naked.

"Looks like i'm going get serious then", you though as you see Jane leaving the bathroom and beginning to flirt with an client.

"Well, here it goes", you yell as you take off your waitress shirt and bra, leaving you completely naked in the cafe ( with the exception of your hat ), much to the happiness of the clients on the cafe, and the shock of Jane, who didn't thought that you'll do something that daring.

"Who want to be served", you say to everyone, upon which, pretty much all of the clients in the cafe raise their hands to you to serve them.

"What ?, you can't be naked here, that's not allowed", exclaimed Jane.

"Actually, as long as you wear a single piece of the uniform, everything else's allowed here, so if you excuse me, me and my hat are going to beat you", you reply confidently to Jane as you recieve tips from a client.

"I need to up my stakes if i am to win this, but how ?", Jane asked to herself as she decided to rethink her strategy. Meanwhile the clients on the cafe where obviously happy to see those two girls undressed like that.

"This cafe is the best", said a guy to his friends.

"Yeah, those beauties are really the best part of it, but the coffee's also nice i guess", his friend repeated.

"I would record them, but i'm busy already editing the other videos", a guy with a cam recorder, whose name's Jerry according to his nametag, says.

"Can i give you a quick grab ?", asked a client of yours.

"Only if you give me double tips", you offer.

"Okay fine", he says as he gives you money and proceeds to feel your ass for a few seconds.

"I guess this isn't as bad as i thought", were your thoughts on that moment.

"Alright, i know what to do", said Jane as she came up with a new way to beat Brianna.
