<human>: So I live with a few other people in a shared dwelling, and we've recently been obliged to settle a matter with our landlord via an arbitration meeting.

I've been in charge of the whole process (which involves a fair bit of reading, photocopying, etc) because I'm familiar with these issues from a past experience (the task doesn't really lend itself well to delegation, it's just enough work for one person, and not nearly enough for two).

I've also wound up being the only person who is going to be able to ATTEND the arbitration, and am thus representing my roommates, as they will be out of town. 

During this process, I've racked up a considerable amount of charges photocopying documents and things, and I've asked if they would be willing to split the cost of the documents and my cab fare to and from the location of the arbitration (no car, not within walking distance given the time, and stuff that I'm required to carry to the meeting).

One of them has agreed to split the cost of the photocopying, but refused to split my cab fare (which will probably add up to about $20, all told, or about $6/7 a person). When I pointed out to him that we would be splitting the cab fare were we all present, he replied that since we AREN'T all going to be present, he isn't going to chip in. 

The arbitration I'm going to could save us about $100/month each if it works out well. I would be doing all the talking whether or not they attended.

Summarize the given text in a few sentences.
<bot>: I'm representing myself and some friends at a legal meeting that they cannot attend. They agree to split the cost of preparing the documents, but refuse to split the cab because they won't be coming with me. Thoughts?
