Are you able to get online at work to prove that you did get back in town at a pre-established time? A time that two people might establish in order to determine whether one or the other owes $5 to the site or not?
Plan is to be back at work by 10...so yes, I can login to RCF then. Not sure how we could conclusively establish that I was where I said I was short of trusting me though...
Note that I'm intentionally ignoring the direction the conversation went after you posted this
