/reserve documentation

[danwie]

/reserve is a powerful command. But it seems to be lacking some documentation. There are some scenarios that needs to be clarified.

What happens if:

• there is already available bag when I use the reserve command, will the system book this bag?
• if the system book a bag, can I change my mind? For example: what if i have several reservations and they all get available and booked automatically, and pickup time have already started. What are the rules of cancelling bags?
• if I reserve several bags from same place, will the system merge them and try to book them together. Or will I get three separate bookings? If separate, do I need to cancel them and then then do my own new order in order to merge them?
