Sometimes it's hard to find a cab.
I think the jobs @ chex serve as an outlet for the mechanic/driver archetype in-game. Which there may be other resources available to cater to that sort of thing, an NPC based organization can always provide a fall back in case of...bankruptcy?
I don't understand the necessity of taxi stands, but I've got no qualm against them.
Pay phones, however, I would love to see...only if they're transparent though. Yes, with the grid...with everything. Big brother, baby. Who loves you!
Or perhaps just making the telepresence units on GOLD able to call Chex / Aero as well as each other.. I dunno. Ideas?
